Custom MOBO.
Now, this subject made me remember (apparently) Supermicro do custom motherboards, even just one.

Would be interesting to try a very minimal motherboard with a very low clocked processor, PCIe M.2 support (or even DOM module), RDIMM, and with just a IMPI/serial console as "extra" feature - no graphic card.

But the main point would be the possibility to try to have the board made using linear regulators instead of the usual switching ones, if possible.

Now, a interesting point is: would SPF+ do bring better results (sound-wise) for network stored music than Ethernet?

Lampizator sell this "Komputer" product: http://lampizator.eu/Fikus/KOMPUTER_-_MUSIC_SERVER.html

Komputer_Lampizator.jpg

The only thing would interest me on it is the power supply and maybe the box. I do not care at all about the software he is using on it, and ever less for Asus consumer MOBO.

I will evolve this idea later.

Hm, I do not think I ever said it ether. As a software engineer I have for sure expertise but: I am absolutely ignorant in computer hardware and I did nothing serious in my professional life with sound processing. So under no circumstances I would feel that I have any advantages over anybody else in construction of DAW. In fact when I did it I was shooting absolutely blind and I have make any claims how performance of my DAW relates to performants any other DAWs out there. So, please, let be sane about it.

Ok, sorry, that affirmation was a mistake then.

Aurender N10

It has some many variables involved what make in practice very "system dependent".

A CD transport follow (more or less) a constant design, while each PC can have so many differences between each other it is impossible to make a statement.

At the (normal) PC side we have several parts¹: motherboard (with several different parts in it), fans, ssd/hdd, PSU, processor, memory (I use RDIMM only), etc. all of them can contribute for the result, specially with noise, and none of then was designed with audio in mind. Well, there are the audio cards but everyday day people use more and more USB DACs.

IMHO, the only way to avail it with (more or less) parity between them would be using a proper built DAW² or a commercially available DAW. Something like Aurender N10 should be interesting to add in the mix, because it has a FPBA and seem quite well made.

¹not to say OS, files system, BIOS/UEFI, drivers...

i have heard the Aurender N10 is not good

What is the problem with N10?
Armir,

I did not heard the N10, what you did not like in it? It is terrible or something more specific?

I dont judge audio products by it's spec or magazine reviews.
i guess it's sound is not my cup of tea.

Please, elaborate.
There is a difference between something that sound bad (faulty) and something I do not like (taste) - what "it is not my cup of tea" means.

Since you previously said it is not good I assumed you found out it is a faulty product, but apparently you think it is not, it more like a taste thing.

So, may you elaborate a bit more about what characteristics you did not like on Aurender sound?

when a reviewer say the component sounds precise i guess it means the sound is compress.

OSS.
OSS over ALSA everyday, specially the FreeBSD implementation. The only issue with OSS is the lack of drivers, there are very little drivers when compared to ALSA.

Pulse Audio is purely crap and almost useless, or complete useless if you compare it with OSS what offer alone all features ALSA + PulseAudio.

Jack only stream on fixed bitrate.

Audiophile Linux.
You can try: https://www.ap-linux.com/ instead. I think there is not anything special on Voyager, it is just tweaked to use very little space what is not a problem on that board. You can easily find a CompactFlash card with 64GB, what is a lot more more than you need.

If you have some patience, you can make www.runeaudio.com work on X86 too.

EDIT: if you wanna run mpd exclusively, you may be better with NetBSD. I think you should not have driver problems with those boards nor with the SOtM card.

EDIT: to make mpd work bit perfect you just need to configure it to grab the hardware directly (for instance hw:0,0) and not the software mixer: dmix or pulseaudio. When mpd (or anything) grab the hardware nothing more can play sounds while mpd is playing - unless you are using pro audio cards with several channels.

To find the hardware, using Alsa (i.e):

% aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: Generic Analog [Generic Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: Generic Digital [Generic Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


If you want to use (i.e) "Generic Analog", Card 0 Device 0, you should configure mpd to use: hw:0,0.

Runeaudio
Ap-linux needs more memory than voyage and alix memory size is just 256mb.I am not pro linux user , my friend install and config linux on my board. i am not sure but i guess Runeaudio just works on arm processors like BBB and installing it on x86 is not easy .I never heard any bad news about voyage and i think linux is not important if we config player/alsa to work in bit-perfect mode. I use mpd 0.17 with asynchronous usb to spdif berkeley alpha.
Thanks a million

Rune Audio are just tweaks.
You can run RuneAudio on anything Linux. You would just basically need to get the config files and put it on the right place. To run the nice Rune interface, what basically is a php website, you would just need to install some very light  webserver like httpd + php, and put the files on the right place. Easy but one would need to have some patience... I will eventually do it, maybe.

NetBSD is not Linux, it is a FreeBSD fork aiming embedded devices specifically. It does not have only minor tweaks, like the usual Linux distros, it is a proper OS redesign for that objective, however still compatible with FreeBSD. You should use OSS for audio in there.

EDIT: you can use that board with the SOtM card in a thin chassis if you prefer. You would just need to grab a chassis which support riser cards, like this one, and a riser card.

it seems i should learn more about linux for running runeaudio on x86 Alix board. volumio is also works for x86 platforms but i have no idea about it.
if runeaudio works bitperfect then why i should install NetBSD?

Optimizations
NetBSD have a lot of specific optimizations for embedded systems, including several ones to reduce the wear flash cards, for instance.  It is also more stable and have a more sane update/upgrade schedule, and it uses OSS by default.

You can also have several cards, each one with a different installation and so you can test everything without bother the other ones. :-D

EDIT: Yes, Volumio have a x86 image already, should end up the same of Rune Audio in practice. I wasn't aware of it.

You can also install everything thing in a VM, like VirtualBox, to feel how they work.

The locus of intervention
Guys, it is worth thinking about where the computer attributable noise is best intercepted. Since the signal is digital all the way to the DAC, it is sufficient to optoisolate the USB connection. If your DAC runs the USB traffic asynchronously all the jitter will come from the DAC alone. So it will not matter at all what you run on the computer side.
