ProJect MaiA Review – the shrunken integrated amp / DAC
Friday, 19 June 2015
"Portable" Project Part One
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 |
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 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.

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
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.
