How about trying "Google" first !??! It really helps
to get your base knowledge settled.From my experience: There's no such thing like the "Pi-Menu for Audiophiles".
"sound quality", as usual, is a pretty subjective and relative matter.
You basically can't trust anybody!A RPI project won't be a simple plugn' play exercise if you look for
high quality audio.As FMAK suggests, the out-of-the-box PI is all but a great USB
transport. A good PS and using an e.g. iPurifier2 or similar USB
regenerator will improve the situation and IMO are a must.
Or you settle with quite a nice HAT DAC, such as MamboBerry
or Audiophonics iSabre. USB issues will be gone with these.As Archimago suggests, the Odroid-C2 is the much better HW choice.
The Odroid XU4 is probably even better as USB transport.
Unfortunately kernel/firmware/community support is ways behind RPI.
This alone disqualifies the Odroid C2/XU4 for the time being for me.
Odroid though is well aware of the issue and trying hard to improve.
It seems that they managed to get several board related drivers
merged into the most current so called mainline kernel tree (4.7).
Which is the generic kernel tree!! This is great. From what I read
though, they are not 100% done yet.Just installing Volumio, Rune or Moode Audio won't do either.
If you want to achieve quality levels like (or close to) e.g.
the MicroRendu you need to get into the depths of Linux
modifications.
Meanwhile pretty much all these distros are gaining heavy weight with every release. Obviously everyone tries to widen the customer base.
Usually putting more stuff in though, goes hand in hand, with lowering your sound quality.One more thing I'd like to mention. The ARM fraction, has its limitations.
I wouldn't run high load server tasks and challenging DSP tasks (SRC)
on these tiny boards.Bottom line.
From my experience, the RPI can do a real great job...
...if you put some work into the setup and if you're willing to accept certain limitations.Even with the mediocre HW, to me the RPI is still the ARM board of choice.
SW and community support is the best and most advanced out there.
And that's what matters to me most on the long run.From an audio perspective I'm quite satisfied with my "tweaked" RPI setup. And I don't see a reason to switch platforms. Challeging DSP tasks I'm running on a dedicated server (NUC).
I just hope that the PI folks one day come up with a HW a la Odroid. The HW really has space for improvement. On the other hand Hardkernel/Odroid seems to be catching up with kernel/firmware work. As soon as I have the feeling that they managed to catch up, I might give it a try.
Good luck.
