Scalford 2014 - The Wigwam Hifi Show Report

IT'S DIFFERENT

The Hifi Wigwam Hifi show is like no other.  50 rooms of systems set up by enthusiasts in an hotel in the UK Midlands to play music for other enthusiasts.

What's the point of that?  Well variety seems to be the watchword.  There's nowhere else where you'll be able to hear so many different approaches to music playing in one day.  And all of it is independent of the manufacturers.  Don't take that to mean impartial - its far from that as the Wam is famous for the views of its members, and their enthusiasm to express those views.

Every room is very different (although you'll hear lots of ways of hanging vinyl, valves and horn speakers together), and tackles what the exhibitor thinks is a good way of playing music at home.  Some of the rooms are very challenging (think hard walls with no furniture, or tiny hotel bedrooms with bouncy chipboard floorboards and sound bleeding through from the next room), and getting a system working even slightly close to its potential is often many hours of setting up work.  Its a lot of work going to exhibit, lots of kit to be transported across the country, carried up stairs, positioned, re-positioned and then re-positioned again, take it all apart, transport it again.

WHY?

Its a strange thing, trying to figure out why anyone does this.  There's no money in it for the exhibitors, in fact it costs money - as a minimum for the liability insurance, and for those in the larger rooms, the additional fee for a large room plus the cost of getting there, staying in the hotel and, the inevitable, beer money.  Is it the community?  Possibly - despite the outward appearances on the Wigwam forum, they're just a bunch of enthusiasts trying to get the best out of their (perhaps I should be saying "our", being a Wammer myself) music playing kit, and to learn from each other.  Is it to gather affirmation of their ability to build / assemble and excellent solution?  Also a possibility, but given the opportunity to produce a rubbish sound in some of these challenging rooms, it hardly seems likely.  Is it altruism, offering to help others decide how to build a good music playing system?  More possibilities here.  What about just extending the idea of the Wammer gathering when a few get together and compare various bits of kit in one of their homes?  There are probably more reasons too, but I suspect it is mainly a combination of the above for most, with other reasons thrown in (such as an excuse to get away for the weekend with like minded folk and drink beer whilst having a good old natter.  There's certainly a community atmosphere about the place, and there's certainly a chance to help others (e.g. one year there was a Wammer there offering to test valves for correct operation).

TAKING PART

This year was my 3rd pie-fi show (it's near Melton Mowbray).  The first year I attended with Richard and John as visitors.  Some systems we enjoyed, some we hated, some were so-so.  And so it will be every year and for every visitor - but every visitor will have a different list of systems in each of those categories.  In every room, joy for one visitor may well be apathy for the next.  What is a constant is the effort put in by exhibitors, and the risk of a disappointing sound.  So even in the rooms where you're less then enamoured by the sound you hear, its always good to remember all that hard work, and acknowledge or thank each and every exhibitor you encounter.

Last year was the first time exhibiting.  Richard and I took my all-Linn active streamer based system.  Partially this was because I thought there would be interest in this as something different (there had been no all-Linn systems at any of the previous 4 iterations of the show) and partially because I really think that system has a lot to offer in terms of musical enjoyment.  To be fair, there was also the fun part of taking something that many Wammers think has very little to no merit as a solution, nor as a brand.  You can read about the results here.

So what to do this year?  It didn't take long to decide to exhibit again, but with the over-riding attraction of Scalford being variety, it seemed appropriate to do something different to last year.  Having more than one system around the house makes this possible.  So this time I wanted to go for something less expensive, yet something again that was new or different for the show.  What would it be?  In the late Summer of 2013 and idea started to form and it was based around taking a Yello "virtual concert" DVD with me to a fellow Linn forum member's house to watch / listen to on his Linn system.  This DVD is excellent sound quality, superb imagery and Yello is a perennial favourite at hifi shows.  The idea was off and running.  A post up on the Wam indicated that there was some interest in a visual presentation, but it wasn't exactly an overwhelmingly positive response.

Sticking with the cost effective route, I put together the following system, after a bit of a test session (read about it here), and the application for a room went in.  As new exhibitors get preference, and that I was proposing something a little unusual, I kind of expected to not be offered a room this year.  Selection is by a very small committee - its not a democracy, and that's fine.  If it turns into a democracy we'd never see a show happen at all.

Sony BD-S480 Blu-ray as transport
Linn Akurate Kontrol/0 Dynamik as DAC and pre-amp
Rotel RB970BX power amp
Mission 773e speakers
Q Acoustics 2070Si sub
Dell M410HD projector & room whiteboard
Chord Prodac Pro Gold digital coax interconnect
Linn Silver analogue interconnect
Linn K20 speaker cable
Clearer Audio Copper Alpha HDMI cable
Clearer Audio Copper Alpha distribution block and mains cables
Quadraspire and Cyrus / Mission Isoplat system support
Atacama SE20 speaker stand for the projector

I also had a projector screen on stand by, but was hoping to get a room with a large flat wall or a whiteboard to work with.  The Linn DAC / pre-amp probably doesn't qualify as cost effective, but you can't have it all ways when putting something together just for a weekend.

The music choice was easy - we would play the Touch Yello Virtual Concert on a loop all day - it plays for about 40 minutes, but most people only stay in the rooms for 5 minutes or so, so that's not a problem.  Well, at least I thought it was an easy choice, but Richard was a bit less confident, which made me less confident, but it was kind of too late, as the application had gone in.

Having exhibited the previous year, this year was somewhat easier.  Dig out last year's spreadsheet and swap out the kit names etc. Make sure the right spares reflected the system in use and make sure there are adequate boxes to protect the kit in transit.  Having lighter speakers this year seemed to be a good thing - carrying last year's up the 2 staircases was hard work.  Hadn't factored in that they're boxed as a pair though...  We were successful in getting a room (again up on the 2nd floor in the main hotel building), so down to work.  Accommodation booked, Saturday night curry booked and pork pies ordered for my room assistants.

THE WEEKEND ARRIVES

All boxed up by Thursday night before the show, signs printed (room door, kit list in the room, and signs to help visitors actually find the 2nd floor in the main building), stuff like biscuits and water for the room sorted and other sundry practicalities to deal with.  Yet again it all looked like an huge amount of kit, stacked up in the hallway and our lounge.  Was it all going to fit into the car?  Saturday arrived - decent weather and all the kit squeezed into the car at the second attempt.  Actually a bit more space left than last year, Richard came over and we set off on the 2.5 hours cross-country.

When you get to Scalford it all gets a bit surreal.  There's folks and boxes and vans and trollies everywhere.  Its all very purposeful.  There are also plenty of folks already at the bar...  We take about an hour to get everything up to the room and out of its boxes, with the help of brother John and fellow Wammer Rick who happened to be passing and offered to lift n shift - all part of the community spirit.  We spent about 10 minutes discussing the layout of the room then got to setting up.  About 30 minutes later we had music playing and a picture on the very conveniently located whiteboard.  Speakers were moved around several times until they balanced well in the room, then we added a very subtle assistance from the subwoofer - again a few adjustments and we were done in under 2.5 hours.  Still seemed a long time, but worth the effort.  With cables taped down and signs up on the walls we were off to the bar to get refreshments.

On the Saturday evening there's a really relaxed atmosphere about the place as Wammers (with beer in hand) wander around to see who's set up yet and drop in for a listen.  The surreal vibe continues - you don't know which rooms will be ready, where they are (the place is a rabbit warren) and what they'll be playing.  Unlike Sunday when everything is very very busy, Saturday is chilled and easy going.  There's good banter and the occasionally panicking Wammer trying to fix a problem or borrow a bit of cable from somewhere.  Just meander around and drop in - you're always welcome.  Bizarre though - who would ever think of running a pair of Quad ESL 63s in a bedroom for example?  With the bed still in there!  Everyone is both opinionated and friendly at the same time.  Then there's the curry buffet and more beers with more listening to be done.  As an exhibitor this is the best time to get around and hear some music.  Sunday will be a bit manic in comparison.

SUNDAY

Up around 8am, showered and down for breakfast.  The bedrooms at Scalford are functional.  There's a new owner now (must've been a bit of a shell-shock, taking over the reins on Friday then touring around the rooms over the weekend, seeing what goes on over the Hifi Show weekend) - lets hope it doesn't get too posh.  Whilst a refurb would be a good thing, if it gets too posh it'll get too expensive for many exhibitors and perhaps the economics of the show will no longer stack up.  Lets hope a good balance is maintained.

Breakfast is busy and there's lots more boxes of kit making their way into the hotel.  More helping going on.  There are lots of volunteers about the place - running the show, manning the ticket table, setting up the raffle, handing out the exhibitor badges, just running the whole thing or mucking in wherever required.  And the ever tolerant and helpful hotel staff who probably wonder what's hit them.  We finish off putting a few more signs up on doors and as directions then check out of the bedroom and prepare for the day.  Our first visitors are in at 9:40 (the show opens at 10!) whilst we're still taping up some extra materials to help black-out the windows.

We take turns to look after the room and advise visitors on the kit and the artist (surprisingly, a good number are new to Yello), how much it cost, who makes the projector etc. etc.  We get some good feedback, we get polite nods and we get folk who don't acknowledge that you exist (grrr, you don't have to like what we're playing but you could at least be polite).  We get a few moments of a completely empty room, but that's few and far between.  Most of the time there are between 6 and 10 visitors in the room.  Some put their heads around the door and don't come in, some stay for 5-15 minutes (this is the majority) and some stay for a full cycle of 40 minutes.  We have a good 10 or so who come back for more later in the day (or maybe more, I wasn't in the room all day to know who was a re-visit and who wasn't, in some cases).

Having 2 assistants to look after the room during the day meant a good amount of time to get about the other rooms too, which was really appreciated.  There were many interesting exhibits such as Serge's quadraphonics, the professional reel-to-reel tape decks, fantastic DIY kit, some amazing workmanship in wood etc.  I didn't get around to all the rooms but I particularly enjoyed the Jolida / Muhlidine system, Myrman's Zingalis (suffering from the boominess in the room, but cutting through that), the Wadia / Krell / Wilson Audio system making the best of a very large and reverberant room and the LP12 / Naim / Neat MF7 system.  Hearingisbelieving (Chris) was getting exceptional results in what must be one of the worst excuses for a room ever - the T+A speakers coping well in what is effectively a wide corridor.  I'm sure there were other highlights, but I either missed them, or they've slipped my mind for the moment.

Its amazing how quickly the 7 hours goes by.  But by 16:45 we had an empty room and decided to start packing up.  About 10 minutes in we had to disappoint some visitors who were still making their rounds, so apologies to them.  Took us one hour (6 hands make light work) to get everything into boxes and packed into the car.  Stirling work by Richard and John after a long day, they made the weekend much more enjoyable in terms of a shared experience, good banter, company when touring the rooms etc. - thanks very much to both of them (although I have a sneaking suspicion they had a good time too).  Also many thanks to all the Wammers who make this happen, and to the hotel staff for their cheerfulness and tolerance.  And to the raffle organisers - I came away with a SIM2 projector, so very pleased with that, but also for them raising approx. £2000 for cancer charities.  Excellent.

Another 2.5 hours in the car in torrential rain saw us home again safely, boxes out of the car, then collapse and ready for sleep.  A very exhausting weekend, but somehow very enjoyable.

One final thanks - and the most important one for me - to my wife and kids for letting me spend such valuable weekend time doing something quite so off-beat as the Wam show.

Now, what's the plan for 2015?   :-)

AND FINALLY, SOME FEEDBACK FROM AROUND THE FORUMS

From Cyrusunofficial.co.uk :

abozo: TBH Yello isn't my taste in music but I have to admit that the sound in sunbeamgls's room was startlingly good.  A very nice setup and those Mission speakers were outdoing themselves. 

Moz: I think you got a great sound out of those Missions. Enjoyed my time listening and viewing. Thanks for exhibiting.

callen24: +1 so good where those missions that in the dark I thought they were £15k linn actives, yello isn't my cup of tea, but stop make sense, or some other classic concert film would float my boat.
the whole idea improved the show, still hifi , and not AV

hifinutt: I think sunbeams system was a real hit with many , it was so enjoyable and sounded better for knowing it was such a reasonable cost

Brumjam: The room showing Yello through a Mission system was another highlight.

From forums.linn.co.uk :

Slackboy: Sunbeam's room was cool; nothing like anything else there, which was great in itself. I was surprised at how crisp that Rotel/Mission pairing was, especially on percussion - very nice. I'm not all that much of a Yello fan, but I did enjoy something to look at other than a load of (other) middle-aged blokes with beer bellies. Great idea and well done. Very inspiring!

Dasher: I enjoyed your AV too even though I too am to a great Yello fan.

From hifiwigwam.com :

cobbler: great fun and loved the concept of a themed room.

petethefeet: Loved the setup in there, inspired. A real experience.

Turn It Up!: I think my Yello days are long behind me but fair play to you for the all out Yello only playback. Nice to see some visuals, be good to have a few other exhibitors get some screens running.

Beobloke: Fine sounding setup and I loved the Yello concert – a very novel idea.

sligolad: Met Niall(Neill), John and Friend at the saturday night curry. Great lads and fellow bikers as well but when Niall explained the system I though this is a bit ridiculous why bother doing it. Changed my mind when I saw the quality of picture and sound achieved with a small budget.

JANDL100: Sunbeamgls's Yello Touch virtual DVD concert on permanent repeat. A great idea. Fab.

themadlatvian: Actually I greatly enjoyed your Linn system the previous year, so I wasn't surprised when you came up with a musically pleasing room this time. I know the limitations of the 773es from personal experience, but you got far more out of them than I expected.

Preparing for The Hifi Show at Scalford on 2nd March

I've been successful in the allocations of rooms at the Scalford Hifi Show again this year, so planning is underway.  This show is for enthusiasts' systems - its not commercial, its just for the sake of listening to lots of different systems (about 50 again this year) and lots of different music all in one place on the same day.  Some of it will be very esoteric, some prosaic, some weird and some DIY.  Variety is the spice of this particular show.

Having played the main system last year I'm doing something different this year, going for a 2.1 AV setup.  My intention is to play the "Touch Yello" DVD on repeat all day - each run takes about 45 minutes.  Yello tends to be popular at this type of event, but I don't think Scalford has seen an AV solution before, so it will be interesting to see how popular the room is.  Originally I was thinking of being very amitious and going with a 5.1 system.  But the Yello soundtrack is only in 2.0, so there's no point really.  Maybe another year.

The proposed kit is much more prosaic than the main Linn system and consists of:

Sony S480 blu-ray player
Linn Akurate Kontrol/0/D (mainly being used for its excellent internal DAC)
NAD 2155 or Rotel RB970BX power amp
Optional Q Acoustics 2070Si subwoofer
DELL M410HD projector and screen

As part of the planning I set up the various components in the kid's playroom (lots of space, but unfortunately 3 walls of windows) to decide on NAD vs Rotel power amps and to check the subwoofer's integration with the Missions.

Testing Time
 So with lots of power, HDMI and audio cables strewn across the room, Yello was spooled up on the Sony (its the extremely slim box bottom right of the picture).  The NAD amp was OK, but a bit sluggish and lightweight.  The Rotel beefed things up nicely and moved along at a better pace with somewhat smoother and more detailed treble.  So that decision was quick and easy.  The system still sounds pretty bright (but not harsh) and I'm hoping that's down to the nature of the room - all that glass is very reflective of high frequencies.
Next the subwoofer was unpacked and plugged in (not shown in the picture above).  It took a while to get it all working smoothly together, but, in this room, it worked well.  Using the "music" setting rather than "movies" and with the crossover point at around 70Hz a good amount of non-flappy weight was added to the sound, and the brightness was balanced somewhat too (but still not enough for my taste).
So we'll see how well the sub integrates in the room at Scalford, but its definitely coming along as I'd prefer to use it if I can.   Hopefully the lack of glass at Scalford will help somewhat too.

Meanwhile, In The World of Multi-Channel

I run a pre-pro in my system (a combined pre-amplifier and surround processor that needs to be connected to multiple power amps rather than having built-in power amps) as I like the idea of one decent quality system rather than splitting funds between AV and music systems (although if I had a big enough house and I'd won the lottery, that's exactly what I'd do).

Unfortunately, there's a restricted choice of such products out in the market.  I've used a Meridian Pro-Logic pre-pro for about 11 years and have recently moved to a Linn AV5103.  However, Linn are out of that market and Meridian are only producing products in the stratosphere.

So that leaves Rotel (good value), Arcam (apparently a great product, but not exactly budget) and other esoterics such as Parasound.  Now Bryston has a new product called the SP-3, launching at the Bristol Show later this month.  It won't be a bargain, but its good to see some more choice.  I look forward to trying to find a review!

Manchester HiFi Show October 2011



The Manchester show is a regular now and is "supported" by Sevenoaks, so the vendors there are those that are available through those dealers plus a couple of extras such as HiFi+ and What HiFi magazines - the latter publicly announcing their 2011 award winners at the show.  Whilst on that subject, they've actually got a category for streamers now, which is great news for the profile of these sources and they awarded the under £1000 and overall award to the Cambridge Audio NP30, the £1000 to £2500 award to the Cyrus Stream XP and the over £2500 award to the Naim NDX.  Nice spread of prices and manufacturers there, and you can see my thoughts on the Cyrus and the Naim earlier in the blog.  Nice to know that I've bought a streamer that sounds much better than the highest priced award winner.  Bit odd that, given that WHF have reviewed the new Linn Akurate DS/1, but they only did this in a complete Linn system.  They should have some consistency with their product reviews and put each through a number of system combinations to test them in identical conditions.  I guess that's a bit too obvious and probably messes with agreements between mags and manufacturers that are delicate and full of politics...

Anyway, back to the show.  First off, its £7 for an adult.  That might seem a bit strange to pay to go into what is effectively a big shop, but I did feel as though I'd had a good day's entertainment (maybe this says more about me than the show!) and I think it probably helps to ensure that the attendees are at least interested and not just going along for a freebie.  The show was well organised with plenty of signs and staff on hand to help out.  Only the food queue over lunchtime was a bit slow, but at least the food wasn't rip-off prices, given that it was in a large hotel.  I thought the Renaissance Hotel itsself feels a bit tired and ready for a good spruce up.  I wouldn't like to have had a hangover and had to deal with the geometric pattern on the carpet in the Kef room.  Speaking of which, I think many of the exhibitors had enjoyed themselves somewhat on Saturday night, stories of being up until 3am and 4am were quite common this morning!

There were some good bargains available if you were in the mood to buy and you were after what was discounted. Castle Knight speakers at half price, 30% off a Rotel RCX 1500 AV receiver, £60 off a Panasonic blu-ray and up to 15% off everything else.

In the main foyer, there was a stall and lots of boxes of bargains and a good spread of Naim's latest products - not playing music, but they did have 2 rooms elsewhere in the show that were playing something, but more of that later.  There were then a couple of large rooms with various manufacturers spread around the periphery - these included Cyrus who had a whole corner to themselves, but were only playing music quietly, the room being unsuitable for demos - what a disappointment, as they weren't playing music anywhere else in the show - I like Cyrus kit, but this was not good - we don't want to look at the kit (you can do that in a magazine), we want to hear it.  Sonos and Simple Audio were in these larger rooms too - pointless.  These rooms are suitable for accessorise such as HiFi Racks and Chord cables who were in there, but not for serious manufacturers - get somewhere to play your gear guys!

In a central lounge area you could get snacks and drinks and Pioneer were demoing a couple of iPod boom boxes.  Over lunchtime a cellist played for a while and very good she was too.  Off this room were 2 large dem rooms - Samsung and Pioneer, with Samsung operating a theatre style with timed "shows".  KEF were running a similar approach, as were What HiFi who had brought a portable room for their demos.  Above that were 3 floors of bedrooms of various sizes that had been stripped of most of their furniture with the en-suite rooms acting as store rooms.


So that's the set up.  After the initial disappointment of a quick look around the Cyrus stand (and looking at all their identical boxes - what's the point?  Let's hear them!  OK, I'll leave that one now, honest) I stepped into the first KEF demo of the afternoon.  They are celebrating their 50th anniversary so they had some of their "iconic" products of the past such as the K1 Slimline104 and the 105.4 dotted around the room.  Using a Denon CD spinner that I didn't get the details of, Electocompaniet Classic 4.9 pre and Electrocompaniet Nemo monoblock power amps, KEF demonstrated their new flagship £20k Blade speakers.  Simply put, this system sounded stunning.  The imaging width, accuracy and depth is the best I've heard anywhere (including Quad electrostatics), the music flows and everything seemed joined up - no harshness, no flabby bass, no swamping of voices, just very, very good.  Anyone got approx £45k to part with?  Getting a bit more back to reality KEF followed this up with a quick play of the new R series - starting with the £1500 R500 floorstanders and then the £1000 R300 standmounts.  These were powered by what looked to me like an Electrocompaniet ECC-1 CD player and an ECI 5MkII integrated.  The floorstanders were OK, but the standmounters were punching well above their weight playing some Maroon 5.

Electocompaniet In The KEF Room (hangover and this carpet do not make a good combo)

KEF Blade (R500 and R300 in the background)

After this I wandered around the dems going on in the 3 floors of bedrooms.  Here are some snapshots:

Neat were playing their new £650 micro speaker the Iota - it was very musical and, in traditional Neat style, produced more bass than you'd think from so small a box, but perhaps they've gone too far this time as despite this, they're still compomised.  You'd have to be very short on space to go with this one.  Shame the didn't have their XL10s to listen to.

Yamaha were playing their award winning soundbar and that's a pretty good special effect they've got going on there - could be one for the dining room tv as its sound is compomised but its position in the room doesn't lend itsself to positioning between a decent pair of speakers.

Naim had 2 rooms up and running, both of which I found particularly pointless.  Why is this?  Because they were using their own speakers - the Ovator S-400 in both cases.  One room had the SuperUniti, the other a high end combination of their lower-end range (if that makes any sense!) - the ND5 XS streamer, NAC 152 XS pre-amp, NAP 155 XS power amp and Flatcap XS power supply (not sure what it was powering).  The XS system was making better noises than the SuperUniti, but with those speakers, noises is all I can say they were making.  I really like Naim electronics (see Pro-Ac comments later), but with the Ovator speakers the sound is hard, lacking in depth or warmth, very two dimensional and completely uninvolving. Do they make the cabinets out of plastic and the drivers out of cardboard from cereal boxes? I know this is just a very personal opinion, but there weren't many punters staying more than a minute or two in either room.  Shame.

REL had 2 rooms too.  One with 4 subwoofers supporting an AV system of some sort (it was dark in there!).  One subwoofer was on the centre channel, two on the main speakers and one on the rears.  We watched clips from Bolt and for a cinema system this was particularly impressive - lots of very well controlled and steered explosions, rumbles and bangs.  Good stuff.  In their other room a ST reference sub was supporting Audio Research kit feeding Sonus Fabers.  For me the bass was a bit OTT, but I'm pretty sure it could be wound back a bit and make for a really good way to underpin stand mounts.  Having said that, with the huge stands under the Fabers, you might as well have floorstanders and do without the sub...

Audio Research, Sonus Fabers in the REL Room (ST Sub not shown!)
Focal were playing the £8k Diablo Utopia.  Vitus Audio products were powering the Diablos with the SIA-025 integrated amp (£14k) and the SCD 010 CD player (£18k with a top loading sliding door and a puck to put on top of the CD it takes nearly as long to change a disc on this as it does on a Mitchell Orbe turntable) and the unpriced Andromeda speaker cables - these getting my personal award for most interesting / extreme cables in the show.  Initially I found this system to be detailed and with excellent imaging and timing it was all good.  But this was with unfamiliar music.  After a couple more tracks (yes, up to 10 minutes in the same room at this point) I requested some Yello and they put on the Junior B track from the Eye album.  This is where it went a bit wrong.  What's happened to the bottom octave of the disc?  I know standmounters can play this track - I've heard it happen with Neats and Wilson Benesch examples.  Ho-hum.

Focals and Andromeda Cable

Pro-Ac seemed to be pleased with their offering, just playing the music and attracting folks who wanted to hang around in the room and listen. They had the approx £6k Response D40 speakers playing using nothing more exotic than a Naim CD5i and Nait XS.  Take note Naim - here we have a set of speakers that can show off your electronics.  This was the only room I went back to later in the day to listen to some more music, because, KEF top end system aside, this was the best sounding system there today. Well done Pro-Ac.
Pro-Ac Response D40 (spooky!)

More good sounds were coming from what I think was probably the lowest cost system on dem other than those Sonos one box systems and B&W Zeppelins etc.  Marantz had the CD6004 and the 6004 amp driving Castle Knight 1s (normally £300 but available at £150 at the show today).  So a £700 system and this was playing musically too.  They were busy, but I hope they sold some kit today as they proved that you don't have to spend a fortune to get it right you can make more music than some multi-£k systems.

Marantz 6004s with Castle Knight 3
B&W were playing their new £2k stand mount using some classy looking Classe electronics.  Meh.  Wilson Benesch Arcs any day.

Mitchell were playing the Orbe with an SME IV and a Benz L2 and very polite it sounded too.  Maybe the Sweet Baby James album isn't meant to have any dynamics.

Rega had the RP3 turntable spinning and, given it was only playing through the Rega Brio electronics and their curiously small foorstanders it was doing a decent job.  Very detailed and with great female vocals, only a rather strange mix of not very deep yet a bit boomy bass was letting the side down.  Not bad for the price though, and the best sounding vinyl I heard today, not that there was much about to listen too.  Rega launched their Apollo-R top loader CD player which looks pretty funky, but didn't hear it playing.

What HiFi were tracing 33 years of their existence.  They get a lot of grief from more "serious" hifi fans, but we need to recognise that they have decent circulation numbers and they know their readership - make is sharp and short.  At least they're managing to maintain an interest in the industry for the more people than any other mag.  They were running a scheduled 20 minute show which had a great premise but mixed results.  Talking about how hifi had evolved over the 33 years they played a genuine pre-recorded cassetted tape of REM.  It sounded bright, harsh, flat and lacking in bass.  This was followed up by a 24 bit 96kHz track streamed through the Pioneer award winning AV reciever and we got detailed bright, harsh and lacking in bass.  Yuk, I hope this isn't the sound they're looking for when reviewing!  Lets hope the audience don't take this as the way streamed music should sound.  The next demo was much more successful - comparing the grainy, indistinct looking and mushy sounding VHS of the original Star Wars with the latest re-mastered version of the same movie on blu-ray - the up to date disc being massively better, particularly on the 103" £85k Panasonic plasma they were showing it on.  Also good was an action clip using the 3D function on the Panasonic DMP-BDT210 player which was pretty amazing for such a low cost machine.  I'm still not convinced about 3D - there are a couple of things I don't enjoy - one being the stuttering in the picture (rather like earlier LCD displays, before they started refreshing them at 100Hz and higher), the other being that the 3D looks a lot like layers of 2D to me - rather like watching lots of cardboard cut-outs moving around each other.  At the moment a really good 2D display or projector works better for me.

PMC were making a reasonable fist of things with their twenty.24 speakers (£3k) but not really £3k worth of goodness - something about the bass sounded a bit behind the rest of the music.  Lots of very expensive Bryston kit as sources and pre-amp / power amplification.  The whole lot was probably up at £20k and you'd want a lot more wow factor for that kind of cash.

So top "prizes" to KEF and Pro-Ac, wooden spoons to Cyrus (for not playing any music - doh!) and Naim for their continuingly disappointing speakers, masking the excellence of their electronics.

As for the show, would I go again?  Possibly, in maybe 5 years or so when things have changed again.  I think this kind of show has its place, but there were so many rooms which did nothing for me and so few that sounded good, a lot of gear has come in for bad press here.  May be I'm being unfair, but lets be honest - although a hotel room is not the best room in which to show off your kit, they're probably reasonably close to the kind of compromises most of us have to live with in our own homes.  So these rooms are exactly the circumstances in which hifi should be working well if its to work well at home.

Next time I might try Whittlebury for the National show - from the pictures and write-ups it looks less busy and has a less mainstream range of kit to explore.  Maybe.

Squeezebox Touch - Evolution Begins

No changes to the rest of the system (although there is a bit relating to cables...) so this is the first stages of experimentation with streaming audio and how it relates to the Logitech Squeezebox Touch in my system.  For the first part of this story, see the posting First Streaming Times below.
So we are at a Touch on its own into the rest of the system using a pair of Linn Black analogue interconnects.  And it sounds very detailed but flat, lacking space between the instruments, there's little width to the sound and its all lacking somewhat in terms of drive / pace / enthusiasm.  Its fine for background listening, but not so good for listening to music properly.  The CD player is still in a different league.  These comparisons are done between the same CD and the ripped version in FLAC, not against high res files which would be an unfair comparison.
 
Some research revealled that quite a few folks have been running external DACs on their Squeezebox Duets and Touches with some success, and there are various references to different (e.g. Fidelity Audio, Teddy PS) external power supplies making a difference.
There's then a whole separate story about a chance opportunity to go to a Naim dealer when Naim themselves were there demoing loads of kit.  I might write that one up sometime.  But the key relevant point here is that Naim have come out with a streaming device that sounds distinctly unimpressive to me when using its internal DAC, but plug it into the Naim stand alone DAC and it sounds astonishingly good.  Add the external power supply to the external DAC and you have something quite remarkable, but also rather expensive (approx £6.5k at this point).  So this, coupled with the internet chattosphere spurred me on to further experimenting.
I took the plunge and bought a Cambridge Audio DACMagic (for those with an eye for absolute detail, its a black one) along with the CA basic optical digital interconnect.  This is a major step forward and unleashes all sorts of extra information, deeper bass and the soundstage leaps out from between the speakers and pretty much doubles in width.  Hmm, very interesting.  If I then move the interconnect from the CD player (its an AudioQuest Topaz) there are further improvements in control and bass extension.  I purchased a What HiFi recommended Chord Chameleon Silver Plus interconnect (£125) which is an improvement on the Linn, but isn't as good as the Topaz (£180 for 0.5m over 10 years ago, but thrown in when I bought the CD player).
Now if I use the DACMagic and CD player as a transport then the CD player inbuilt DAC still wins out, and that's using an optical digital interconnect (not tried with a coax interconnect yet), so the DACMagic doesn't appear to be as good as the DAC inside the CD player.  Or is it?
The reason for this doubt is because of the next step I took.  I picked up an old coax digital lead that's actually designed for Meridian components to talk to each other, but only for control purposes, so its not exactly designed with sound quality in mind.  However, the improvement of this over the optical digital lead was astonishing.  Optical appears to be rubbish - that could be the Touch output, the DACMagic input, or the cable, or some kind of combination of all or some of these. The biggest difference here is difficult to describe, but if you imagine the "space" around, between and behind instruments is blackness, then the blackness was much blacker - I guess it means there's some kind of digital error correction or hash (jitter?) disappearing from the signal? The music is now going along with some proper drive and pace.  Foot is tapping at last. So if a rubbish cable is better than an optical one, what's a decent cable like?

So in comes a fairly basic but recommended digital coax cable - a QED Performance which is only £30.  Another step forward over the basic coax, but more subtle this time - mainly in the treble area, it's lost some of the remaining grittiness and splash.  Must get around to trying the DACMagic with the CD player transport and the coax interconnect soon, just haven't had the time.
So we're now at Touch - QED coax - DACMagic - Chord Chameleon. 

Comparison with CD player is now getting about 85% of the way there.  CD player still giving a bit more in terms of punch / pace etc, but from a pure detail point of view, there's nothing in it.  CD player still using the Topaz interconnect though, which is somewhat better than the Chord Chameleon.
So off to ebay to find a secondhand Topaz (you can't buy them new anymore).  No luck there, but did find 2 pairs of Audioquest Emerald interconnects which were top of their range at around £230 for 0.5m.  Got them for £40 and £42 so one for the CD and one for the DACMagic.  So here we have yet another improvement to both Touch / DAC and the CD player.  Again its subtle but its definitely there.  How can I describe this one?  Well its a kind of smoothness and flow to the music - whilst the instruments are very seperate and obviously so, the actual music seems to flow along much better and its not a bunch of accurately rendered notes, its a better illusion of a piece of music (I almost used the word accurate there, but we know its not about accuracy, because so few of us actually know what the original performance sounded like and we need to remember that much of the processing done during production is deliberately trying to make the recording NOT sound like the original performance).  This description probably isn't making much sense, that's why I'm not Jimmy Michael Hughes!
So we have Touch - QED Coax - DACMagic - Audioquest Emerald and that's now somewhere between 90 and 95% of the way to the CD player's quality. 

But here are the 2 killer points.  It now stands me at £500 and if I was starting from scratch I'd a choice between that and the £1700 CD player, I know which I'd choose!  But as soon as you add in the ability to play 24 / 96 files then its a hands-down win for the streaming tech - its a good 10% better than the CD player and leads to those evenings that are "just one more track" until its suddenly 1am!

So you have to wonder just how much DAC the Touch can support...
And what about power supplies, and do they matter, once you're no longer using the internal DAC?

First Streaming Times


Having studied the various PC / USB / NAS / Squeezebox / Ethernet / WiFi options for approximately 12 months, I've made the decision to go down the NAS / Ethernet / Streamer route.  I'm interested in this approach as it gives the benefits of no PC nor any spinning hard disks in the listening room, the ability to use mirrored storage in the NAS for back up purposes and only one copy of the music to be accessed from around the house - even across the internet is possible with the QNAP software.
Having been to a few Linn and Naim demos, I knew that it's possible to get very good sound using streaming and accessing NAS over Ethernet.  But I'm not yet ready to spend thousands of pounds on a first try.
More research.  More tests read.  Good reviews of the Logitech Squeezebox Touch and its ridiculously good price whilst being able to deliver FLAC at up to 24 bit / 96kHz looked like a safe way to go. 

This particular story has a bit of background, so if detail is your thing, this should suit you somewhat!

System
CDs ripped using Exact Audio Copy to FLAC, so 16 bit 44.1kHz
FLAC files downloaded from Linn being a mixture of 24 bit 48 kHz and 24 bit 96kHz
QNAP TS 209 II Pro NAS using 2 x 1.5TB mirrored Seagate drives (ARM processor, Linux based firmware)
DELL laptop, Windows 7
Wired Ethernet over Mains
Logitech Squeezebox Touch
Linn black analogue interconnects
Meridian 541 pre-amp
Linn Tunebox Active Crossover
3 x Rotel RB850 power amps
Linn Tri-Active Keilidh speakers
Linn LK600 speaker cable
Comparison against Meridian 508.20 CD player

Software
A mixed bag.  Getting software installed on the NAS is a hit and miss affair, in general, despite them being recommended by Linn - but Linn only required uPnP (e.g. Twonky) and nothing bespoke / proprietary.  The SqueezeCenter server software is, therefore, immediately a compromised situation.  Being reliant on the open source community for QNAP installs means that you need one or more people out there who are enthusiastic about doing what you need to be done. In this case, there only seems to be one person who is producing the required QPKG files (that's the QNAP equivalent to and RPM in the RHEL World or an MSI in the Windows World).  It's therefore a problem if things don't work and that individual hasn't found the time to fix or look at your particular combination of NAS hardware, firmware version, QPKG version and SqueezeCenter version.  I believe the ReadyNAS range has much more support in this area, but having had an earlier Belkin NAS, I didn't want to go there again!  If you are really keen you can go command line and do the Linux install manually and I thought that might be where I might end up.

The QNAP web site is very helpful and has step by step instructions and screenshots on where to find the downloads, where to install them, how to run them etc.  Such a shame then that QNAP have redesigned their website and, of course, our helpful friends in the opensource community have changed some of the help text and instructions since the QNAP instructions were published.  I therefore had to grub around using search terms at the QNAP site (which is a bit hit and miss) to find the right files and to interpret the steps into the current version of the actual steps to take.  So, I downloaded the QPKG file and the QPKG web interface file.  They have to be in a particular directory on the NAS and that was no problem.  I ran the QPKG and it worked OK, but then you have to go off to Squeezebox (Logitech) to get the actual SqueezeCenter software - and even that isn't in a logical place - its actually at mysqueezebox.com which isn't the main Logitech site - for the QNAP box you need the Perl version of this software.  This did install OK through the QPKG software.  However, when running the SqueezeCenter (don't forget to spell it the American way or you'll find nothing!) it failed.  There is a log file which is full of fairly obscure (to me at least) error messages and hints.  However, using the hints in the log and searching for them on the QNAP forum fetched up some answers (one of which included uninstall and reinstall of the NAS firmware - scary!) but it turned out I had a QPKG that was specific to one recent version of SqueezeCenter and needed to download an earlier QPKG that was compatible with early SqueezeCenter versions and the latest version.  So a bit confusing.  It's also a bit disconcerting when running the QPKG files and the NAS tells you that you are now installing a system update...a little unsettling.  Now over 2 hours in!

In the meantime and in parallel...I downloaded the Windows version of SqueezeCenter, installed it on the DELL, pointed it to the correct directory on the NAS and it was all done in about 20 mins, including indexing my music files (but there's only 6 albums of FLAC at the moment).  This allowed me to log into my SqueezeCenter account and make sure all my stuff was ready to go there too (not that there's much to do if you just want vanilla everything), and to plug in the SB Touch and get it up and running.

Touch
This was packed very well and is done in a very restrained but quality way.  The unit itsself is much heavier than I expected and has a solid case and an aluminium stand at the back with soft rubber feet and the whole thing feels very sturdy - there are no nasty plastic moulding edges / flashing etc.  Its very thoroughly wrapped in thin cellophane which is a bit of a challenge to remove.
So, using an Ethernet cable directly to the router and sat alongside the laptop, I plugged in the Touch and switched on.  It immediately identified that later software was available, asked me if I wanted to update and off it went and the software was downloaded automatically and installed in about 5 minutes.  From there it found the (Windows!) SqueezeCentre automatically and there was my (very limited) collection of HQ rips available via album, artist, search etc.  I haven't used the touch screen as navigating via the remote is very easy to use, if a bit cheap feeling in the hand.
Once all up and running the SB Touch was moved down to the listening room and plugged into the Ethernet over mains and the main hifi system using a Linn interconnect.
In my room I'll have to think about where the SB is going to sit - the only currently available position in my rack is a bit restrictive and the screen faces 90 deg to the listening position.  Even so, although the screen is very clear and easy to read, I doubt it will be readable from the listening position.  The interface is easy to follow and very intuitive and I have no problems with it at all.  Very impressive.  I like the info available on each track - you can delve into sample rates, bit rates etc. which helps in comparing sound quality.

Listening
I used exclusively FLAC files as listed above, ripped from my CDs using EAC or, with higher quality files, downloaded from Linn.  Tracks from Jon Strong (Folk Rock), Charles Webster (electronica) from CD and Ian Shaw (Jazz / Rock?) and some piano stuff and female vocal jazz from the Linn sampler downloads.  An Ian Shaw track (A Case of You) I have from Linn in both 24 bit 48kHz and 24 bit 96 kHz formats.  Everything streams fine over the Ethernet over Mains with no dropouts and no obvious artefacts.
So, bearing in mind that its now nearly midnight, listening was not extended and these are very much initial thoughts.  At least I could use a decent volume as the kids were fast asleep and it takes a lot to wake them!  I didn't make direct comparisons with the CD player due to time limitations so observations are from memory of how the CD player sounds and I will report back when I can make actual comparisons - I'll be able to compare CDs against rips of those CDs and CD against downloaded higher res files.  But for now, it seems to me that the SB Touch has very good resolution of detail and has reasonable timing.  However, whilst pretty much all the info is there, it all feels a bit "polite" or "restrained" with tracks lacking some attack and Jon Strong's aggressive acoustic guitar playing (he's from Leeds and is singing about what Thatcher did to the North East so, as you can imagine, this track shouldn't be polite, and isn't on my CD player and definitely isn't when he's playing live with a couple of pints inside!) isn't as meaningful as it should be.  On the female vocal jazz this isn't really an issue as its politely presenting very polite music.  The electronica dance tracks were also restrained and less likely to get your foot tapping, but again the detail is there.
I guess you might remember the "inky blackness" of silence between instruments when moving from vinyl to CD?  Well this device takes that one step further - the lack of noise is stunning and is something I noticed on the Linn DS devices.  I think some might call this dryness or sterility, but I would disagree - it just makes the actual music stand out more.  Also, I noticed that the SB Touch is actually capable of demonstrating the difference between the 24/48 file and 24/96 file of the same Ian Shaw track - very impressive.
Internet radio works - I guess it'll be very sample rate dependent as DAB is.  Favourites are going to be essential here as the choice is a bit overwhelming and could be a few evenings work in itsself - hopefully its possible to manage this through the SqueezeCenter software rather than just through the Touch as the interface isn't good enough to be able to work through the full gamut (sorry Alan) of choice.  There are apps to install too, one of which allows podcast listening so that'll be the first one I give a try.
So a pretty good start.  A more direct comparison will need to be done against the CD player.  However, here's the killer point - the SB Touch was £208 including P&P and the CD player cost £1700 about 10 years ago.  Even at this early stage, I don't think I'd want to swap the CD player for the Touch, but if you were starting from scratch...

If this is the basic level, then the likes of the Cambridge NP30 and stuff coming soon from Cyrus, Arcam et al looks very promising indeed.  Perhaps I don't have to save up for that Linn Akurate DS after all?

Back to the Software
And so the above was all done listening through the Windows SqueezeCenter on the laptop.  However, the NAS version did get up and running, pointed it to the correct folder on the NAS, closed down the Windows SqueezeCenter and started up the NAS version.  SB Touch did find it, but I had to use the "change folder" option on the Touch to point to the new SqueezeCenter instance.  Everything then works well and I did a quick listen to make sure it was working.  Wonder if there's a difference in sound between the NAS and Windows versions???
