ProJect MaiA Review – the shrunken integrated amp / DAC



I like to listen to music most of the time, sometimes its in the background, sometimes it makes a car journey more tolerable, sometimes I’m in the audience and sometimes I sit in front of the main hifi and just focus on listening.  Listening to the artists’ works, sometimes carried away, sometimes confused, sometimes just enjoying the flow, sometimes trying to “get” the message in the lyrics.

And sometimes, I’m away from home (quite frequently, actually).  When travelling by train or plane, I use an iPod or FiiO X3 and earbuds or phones and occasionally I have room in my suitcase for a Logitech Purefi Anywhere 2 for the hotel room.

But when travelling by car, I can take something a little more substantial to the hotel room, and have a large camera case that currently contains a pair of tiny but well made Tangent Evo speakers (no relationship to Evolution Audio, the dealer mentioned in this thread), a Trends TA 10.1 integrated t-amp and the necessary speaker and interconnects to fit to an old-style 30-pin 160GB iPod Classic or anything with a 3.5mm output (such as the FiiO or a phone).  I also carry a work laptop, sometimes used for iPlayer / other catch up services, but not currently for music.  It’s a decent listen and I prefer to listen to music through speakers rather than being tied to a device or location by a device and headphone cables.  Last thing at night, some chill tunes on a 30 minute timer on the iPod often help me get off to sleep in a strange location / room – speakers are far better for this than the need to take off headphones as I drop off to sleep.

Now that the laptop and the phone are part of the entertainment package, something with better connectivity would be useful.  In steps a HiFi Wigwam post from Evolution Audio announcing the Pro-Ject MaiA integrated amp, with analogue, digital (up to 24bit/192kHz), Bluetooth and phono (turntable) inputs.  It probably makes the toast too.  Given that Evo Audio offer a 10 day sale or return service, I thought I’d give it a go.
Now the Trends TA10.1 amp has done very well for me in this system for probably around 5 or 6 years.  Its small, runs cool, its light and has been very robust.  In the camera bag it nestles quite well wrapped in a soft wool scarf, nicely wedged between the speakers – keeping everything tightly packed but not scratching each other.  It does a decent enough job too – way better than most high street “midi” or “mini” systems.  Limitations?  Well, power, but that doesn’t matter in an hotel room when volume is necessarily limited.  Inputs? Yep – there’s only one pair of line level RCA sockets.  Remote control?  Nope.


Unboxing

Evo Audio had shipped the Pro-Ject box, wrapped in a couple of layers of bubble wrap, inside another cardboard box, along with the receipt and an Evo Audio branded pen.  Delivered in reasonable time, it even managed to survive the Hermes courier system undamaged.  Opening the Pro-Ject box revealed the amp, in a plastic bag, contained by “waffle” sponge padding on all 6 sides.  The mains cable, PSU with captive DC output lead and remote control were in a separate sub-box, with no padding around these components.  There is an 8 page instruction leaflet that’s low on content and quality, but is sufficient to get you up and running.  Clearly, the budget needed some corners to be cut, but this is a good place to do so.  The amp itself is very slim (only about 35mm high), around 200mm deep and 210mm wide,  It feels substantial though – the folded steel case and flat alu front panel are decent quality and its very well screwed together.  It gives a good first impression.  Four small rubber feet protect surfaces and help to keep the amp steady on that surface.

Around the back, there are a pair of phono sockets and a binding post for a turntable (yep, there’s and RIAA phono stage crammed in there), 2x pairs of phono sockets for line level inputs, 1x 3.5mm line level input, 1x coax RCA digital input, 2x optical digital inputs and a USB socket (for a PC, rather than an iPod or similar).  Outputs are volume controlled line level 3.5mm, and a pair of small combined binding posts and 4mm banana sockets (which are crammed close together at one end of the panel).  There’s an input for connecting the PSU’s DC cable too.  A lot going on, but clearly labelled, straight forward etc.  I used plastic shrouded 4mm bananas for speaker connections – it’s what I had already, but Paul from Evo advised this type of connection as metal bananas and bare wires are a bit risky with such closely packed connectors.  Generally, those who hoped to use in-your-face mega chunky interconnects / RCAs will be a bit disappointed, and needing to shell out for something more practical.  Bluetooth pairing was straightforward with my Android Samsung phone (Lollipop OS version).

Control

Across the front there is a soft touch power on/off (tiny blue LED indicator), headphone socket, rotary volume control and a row of tiny blue LEDs indicating which source is selected – these are flanked left and right by cursor keys that move the source selection across the row of options.  Clear, simple.  The credit card sized remote gives volume control, source selection, power on/off and the ability to activate Bluetooth pairing.  Its responsive enough, but is necessarily light in weight and functional rather than a pleasure to use.  The main rotary volume control on the amp itself is a little stiff (maybe it will loosen slightly with use – hopefully not too much), but is very smooth and not so stiff that it causes the box to move on a desk.

System

For my first try with the amp (it was on 10 days sale or return remember), I used the following equipment which seems appropriate to the type of use I will put the amp to, and perhaps others will too:


  • FiiO X3 (internal DAC line out and digital coax output)
  • £8 3.5mm to 2x phono interconnect from Amazon (decent build quality, nice tight gold plated connections)
  • 99.99 OFC copper pretty standard speaker cables from Maplin – roughly 42 strand and fitted with soldered on “Shark” 4mm gold plated banana plugs
  • Tangent Evo bookshelf speakers (the ones I would intend to use the amp with) and Mission 773e floorstanders (to better expose differences between line and digital inputs)
  • Music included “Tears Run Dry” by Malia and Boris Blank; “Gaia” by James Taylor; “King” by Tuung; “Rise” by Samantha James; “Doors Unlocked and Open” by Death Cab For Cutie

Listening

I left the amp playing to itself at low volume for about 2 hours – using the FiiO line out and the Evos, just to make sure it was at least warmed through, if not exactly “burnt in”, if that’s necessary at all – its not something I’ve tested so far and won’t be bothering as it seems a bit of an overkill for this kind of product.

Kicking off with the TA10.1 amp, I reminded myself of its capabilities.  Its fast, a touch on the bright side (but not excessively so), and its best listened to at medium volumes – it gets harsh quite quickly as the volume is cranked up, but is a rather dull affair at the lower volume levels.  So about right for the job really, and good value at £110 about 5 years ago.  It has been reviewed in some quarters as a “giant killer” and paired with very exotic speakers on some web sites.  It is astonishingly good for its size and price, but that’s all.  A healthy NAD 3120 from the 1980s shows it a clean pair of heels in terms of musical enjoyment and information extraction, if not exactly neutrality.  Lets just say the TA is great for what it is and is very neutral (with the exception of that slight uplift in the higher frequencies).  But its also rather “grey” to listen to – it doesn’t have much verve or life to it.

Swapping over to the MaiA and it was initially difficult to try and get a perceptually similar volume level.  And that’s because it has a greater perceived (or real, who knows?) dynamic range – the quieter bits are that much quieter than the Trends, but equally, the louder bits are that much louder too.  It better shows through the subtleties the artist has put into the emphasis or de-emphasis of a phrase.  Nice.  So a quick switch back and forth helps to work out where to position each volume control to get as close as I could to something like equality.  Next thing to notice is what appears to be a flatter response – its easy to note that it has less emphasis at the top end, but it is still a touch bright.  Its showing the splashy nature of the FiiO’s DAC well too – this is something I noted when working out which system to go with at Scalford this year – the FiiO’s top end is pretty unruly on the internal DAC.

The MaiA manages somewhat better separation of instruments too – its not epically etching them out, but they are easier to distinguish, as is the location in the image and the stability of that image.  A welcome improvement over the TA.  What of the bass – well, there seems to be a little more of that with the Pro-Ject, and its worth having with the tiny little Tangent speakers.  Music bounces along with a reasonable sense of pace and rhythm.  Its not the last word in refinement, but you can tell the intention is to provide a bit of fun with the music.

DAC

What of the internal DAC?  Well, in this appraisal, I only had the FiiO to hand to compare, but that’s OK, because that’s what I’ll be mostly listening to.  Comparing the FiiO’s internal DAC and line out to the MaiA’s internal DAC again gave some volume control setting challenges.  I didn’t use any equipment to sort this, just a number of back to back comparisons to get a feel for where the control needed to be set.  This comparison did reveal one thing very quickly indeed – the MaiA has a much better controlled and smoother sounding DAC in comparison with the X3.  But it doesn’t image or separate the instruments any better, and has a tendency to suppress female vocals a touch.  Rhythm and pace are still good, with bass perhaps a touch more fulsome than with the X3.  I think it’s a bit swings and roundabouts really, but with the Tangent Evos being a lightweight sounding speaker, the better controlled top end and weightier bottom notes won out for me.  You might come to a different conclusion, so it’s a preferences thing rather than anything clear cut.
Proper Speakers

And what of the performance with the Mission 773e?  These were used at Scalford to reasonably good effect in 2014 and whilst not the last word in lower end speaker technology, they’re effective and enjoyable to listen to.  Normally they are fed by an SBT / MF V-DAC1 / MF V-PSU2 and a Cyrus 6 integrated amp when they’re pretty fast, boogie well and deliver a good performance.  On the MaiA, however, it was quickly noted that all wasn’t what it could be.  That fuller lower end, which worked so well when working with the little Tangents, became somewhat unruly, fat and a bit woolly.  Not great.  The effect was the same with the FiiO’s DAC back in action – slightly less noticeable, but still not really something I’d want to spend a long time listening to.  And the splashiness was back too.

£400

So all this tech and connectivity, squeezed into a small box comes at a very reasonable price.  It would be good to compare this amp with a NAD D3020, and that might be on the agenda at some point in the future.  It fits my use case for it very well, brings a useful increase in sound quality and a massive step up in connectivity and usability.  When the 10 day trial is over, it won’t be going back to the helpful team at Evolution Audio – it already has its place in the camera bag.

So to use this in a kitchen / bedroom / study or as a semi-portable system with a small set of (not too good at lots of bass) budget bookshelf speakers, I would say this amp is a success.  For me, that’s where it does a great job, just don’t expect it to cope as a main system centre piece with a pair of full range speakers.

One final thought – if all that modern connectivity, compact size and sensible pricing gets it into a good number of student bedsits, perhaps a TT connected to some of them, it might well be the way to generate a new set of audio enthusiasts.  Lets just hope they don’t get underwhelmed and miss out on the capabilities of this amp by feeding it a load of compressed MP3 junk data!

"Portable" Project Part One

Look back far enough in the blog and you'll find a bit of nonsense that resulted in a cardboard portable iPod dock using a T-amp and Linn in-ceiling speakers.

It filled a few hours and, although it worked, it sounded pretty rubbish, as might be expectd.  Within a week the taped seams had fallen apart and all the bits were back in their boxes.  So that was that and here is the result, plus the early ideas about building something more substantial, that also came to absolutely nothing, except that the speaker drivers were still around in the garage:  Sneeker Part 2

Although this post and the next 2 parts are being written in the early Summer in the UK, it actually relates back to a project that ran from time to time over the Winter of 2014/2015, I just haven't had time to write it all up.  The actual result made a début in the bar at the 2015 Hifi Wigwam Show at Scalford Hall in Melton Mowbray - providing background music on Saturday evening.

So here are the first parts (the drivers) and thoughts about how to make something more substantial, more Linn and hopefully tolerable to listen to:


Drivers
I thought it through and decided I wanted:

Standard RCA / Phono inputs so it could connect to pretty much any source
Mains powered - batteries are too restrictive
USB charging port to keep iPod or whatever going
Decent volume capability and therefore a proper power amp
Use the drivers already "in stock"
Room to add a Raspberry pi streamer later
Analogue volume control
A "robust" look
Low low cost

Here were the bits I had lying around in the garage that would suit:
4x Mission 100mm mid-bass drivers (see pic above)
Mission tweeters from 773e
Bits of wire
Mains cables
Mission 773e crossovers
T-Amp (which actually went elsewhere before work started, thankfully!)
Bits of wood and wood sheets

So much searching was done on ebay, and I discovered that Linn RoomAmps (from the Knekt multi-room system) sell for very small amounts of money.  I also found that older Linn tweeters sell for a reasonable price too, and ALPs volume controls are cheap, if you can wait for them to arrive from China.

So, the following was assembled:

Linn RoomAmp (£27)
ALPs 10k stereo pot (£12)
USB charger (£3)
Mains switch and socket (£4)
Pair of Linn Index tweeters (£17)
USB socket (£5)
USB cable (£2)
Small black perspex sheet (£3)
z speaker plugs (£7)
Vivarium airvents (£3)

Originally I intended to build a box to put it all into, but my woodworking skills are a bit rubbish, to be honest, so more ebay searching for wood boxes found me something suitable - solid, the right kind of size, and very much fitting in with the "robust" theme.  The box added another £15 to the parts cost.

Some experimenting on the bench with the drivers fitting into a cardboard shoebox indicated that the crossovers worked well with the drivers, and that the RoomAmp was healthy enough, so wood cutting and metal bending started.


Inside the Linn RoomAmp
The RoomAmp is essentially a simple 20-25W per channel power amp - designed to be fitted into cupboards, loft spaces etc.  It has a Knekt proprietary input, a pair of RCA phono outputs and BFA set of speaker outputs.  For the purposes of this project, the "output" phono sockets are used as the inputs - no changes necessary to do this, they're just directly connected to where the Knekt signal has be separated out to go into the power amp, so its simple enough.

The amp has a bent metal sleeve that has overhangs along the long edges.  I removed the sleeve, removed the fillets at the ends with a bit of sawing and power filing (power files - if you don't have one, get one, they're magical!), the overhangs were then bent at 90 degrees to the top panel, forming a lip that could be used for mounting the amp vertically inside the player.  A bit of matt black spray paint was added to prevent rusting.  After fitting the sleeve back onto the amp then a trial fit showed that it worked well inside the box.

Positioning the amp inside the box allowed measurement of where the dividers could be fitted to form the speaker cabinets, where the crossovers could be mounted, how to position the connections panel and where to cut holes for vents.  Holes were then cut for the vents - one in the base to allow cool air in, one in the back to let warm air out, and the vivarium vents were glued in.  The hole was then cut for the connections panel and the 18mm marine ply dividers were cut and fitted, after holes had been drilled to allow the 3 pairs of speaker cables into the speaker cabinet spaces.  At this point all the internal joints were sealed with clear silicon sealant.

Lower cool air inlet vent, one of the divider panels (on the left) and 2 exmaples of how poor my woodworking skills are - good job this is all on the inside

Sealing all the joints with clear silicon sealant

FiiO Fi Fo Fumb

I'm currently on the UK west coast mainline heading for home.  That's good news.

There is more good news, but its not 100% good news.

There's a new portable digital music player on my block and this is its first trip outside Musings Towers.

But what about the iPod?  Well, that's still absolutely going to be my primary portable player - with AAC tracks ripped at 320kbps I get every single one of my 10,000+ tracks onto my 160GB classic, along with lots and lots of interesting podcasts.  As an all in one solution, despite the bloatware that is iTunes, its still pretty much unbeatable.  With 320kbps and the Beyer Dynamic DTX-101 ear buds, it works well, its versatile and sounds more than acceptable.  It also appeals to my lazy side - I don't have to decide which tracks to take with me, or which to leave at home as they're all there all the time.

Under some circumstances, it would be good to take the full fat uncompressed FLAC music experience along for the ride.  This needs a device designed to support this format, with a decent DAC that can handle 24bit files and with sound quality as a fundamental design objective (without which, might as well stick with the reasonable quality available on the iPod).  I could have purchased an iPod and added rockbox, but that would still leave the quality of the headphone amp to be desired, and the inability to play 24 bit tracks.  Astell and Kearn have been producing a decent device, but its price really puts it out of my range in terms of something that's more of a nice to have than a primary device.

So along comes FiiO with the X3, a device that's aiming exactly at what fills this gap for me.  FLAC compatible, 24 bit capable, decent DAC and decent headphone amp.  Add to that the ability to feed a line level output to an amp, or even an electrical SP/DIF signal to a DAC and it starts to look very flexible and worth a try. At a price around 1/3 of existing offerings and it looks like the way to go.  The non-headphone outputs are very interesting from a travelling point of view when I have a car with me, and I'm stopping 2 or more nights somewhere.  The ability to plug into a proper amp and use speakers in an hotel room is very appealling and will the subject of another post soon.  No need to shop around, seems that they're the same price on ebay or Amazon.

Who are FiiO?  They appear to be a Chinese company who are bringing low cost manufacturing to the sector, in addition to nothing particularly innovative, other than stringing some existing technologies into a new and interesting package.

If you're looking for something that's as simple and (relatively) foolproof to work as an iPod, then look away now.  The FiiO X3 isn't there yet, but seems to be making progress...

Its not intuitive like an iPod, the control layout isn't brilliant and the screen brightness &  image quality leave much to be desired. Plus, the process for getting a 64GB micro SD card formatted to work isnt exactly straightforward.  Given that the device has a micro SD slot (there's only 8GB of on board storage), the first thing most owners will want to do is add a card and get it formatted. To have to search the forums so soon is not brilliant.  And theres another challenge.  The firmware is evolving so quickly that the forum discussions are already out of date on some topics. The firmware mine came preloaded with has a menu option to format the card, this seems to be a later addition,  given some of the less that smooth routes some users have had to go through before this option was added to the firmware.  Updating the firmware looks quite straightforward,  but I haven't tried that yet, just getting used to the device first.
Plugging the device into my Dell Latitude Windows 7 PC was painless (using the supplied micro USB cable - some audio cables are also included, but thankfully they don't waste any of your cash on rubbish earbuds, you need to choose your own cans), shows the device storage as drives. Loading music is just a case of copy and paste in Windows Explorer and is a smooth process. Initially I've copied over about 300 tracks, all FLAC format and a mix of mainly 16 bit CD rips and some 24 bit material at different sample rates.
Back on the device and its supposed to recognise new music and update its library automatically.  I'm not sure yet how well it does this as I prompted a refresh of the library via the menu option, just to be sure. Will kerp an eye on this and will report back after a few weeks of use.
Battery life seems decent, running to about 8 hours when using the headphones but seems much longer when using the analogue line out, to the point where it hasn't run down on me yet, before reconnecting to the PC. There is no charger included with the device. I don't have a problem with this as I have USB chargers and cables of a compatible type for my Samsung phone which I carry with me most of the time. It will charge when connected to the PC too.

So to sound quality.  Very briefly, its a major step up from an iPod classic, even when the iPod is playing uncompressed ALAC files. Using either the Beyer Dynamic DTX 101 or the Sennheiser Momentums, the sound is bright, detailed, pacey and dynamic.  Bass goes deep but occasionally is a little boomy, I set the tone controls to -1 on the bass which brings back control. The headphone amp has a switchable high and low output levels so should drive most models adequately.  I find the higher output setting with the volume turned down gives a more substantial sound compared to the lower output with the volume turned up.  Given this excellent sound performance, I was expecting 24 bit to be outstanding.  However, with a bunch of mixed 16 and 24 bit tracks on shuffle, I felt I was remembering which tracks are 24 bit rather than hearing the difference. This difference is much smaller than audible on my Linn streamer in the home system. There are constraints on the capabilities of the headphone output. It will go fairly loud and maintain quality, but well before the volume gets too uncomfortable, the midrange does get congested and vocals become swamped. Bass remains controlled and deep, but the congestion in the mids make for uncomfortable listening. This is similar on the buds and the proper cans, but seems to come in at a slightly earlier point on the cans. But keep the volume reasonable and there's very little to complain about for a device of this small a form factor and price.

Later I'll write about using the line out and digital outs, but for now, I'm going to enjoy some more tunes.

More Cyrus Details

More information on the Cyrus streamer was announced at the Bristol show.  I should've said streamers rather than streamer, as its actually a bit of a family of products.

Lots of connectivity - USB (asychronous or not is not yet clear), iPod dedicated USB, wired Ethernet, WiFi, uPnP and DLNA.  Plus they plays the most important FLAC and WAV file formats up to 24 / 96.

Most impressively, Cyrus have got it right and produced all the main possible combinations for this device:

£1600 Streamline that is streamer / DAC / pre-amp / power amp as an all-in-one mini system (compare Naim UnitiQute)
£1400 Stream X which is the streamer only with digital outputs - so the main "source" component for those of us interested in selecting the best avaible device for each element in the sound reproduction chain (compare Naim NDX)
£2000 Stream XP which is the streamer / DAC / pre-amp version (perhaps compare Musical Fidelity?)

All work with a remote that includes a screen and controls the devices over the network.  Can't see anything in the news (no rear panel photos either) that indicate compatibility with the PSX-R power supply.

Brilliant!  I'm hoping these devices will sound as good or better than the company's existing DAC products (more soon on this topic) but Cyrus have to be absolutely congratulated and encouraged to continue with this excellent approach to covering all the bases.
