Pretty neat! I use a Raspberry Pi 2 with a HiFiBerry DAC+ Pro as a source for my ST-70. It works fantastically!

Hey mazeeff,

Can you explain a little more about your setup? It sounds intriguing. Are you using this to play music wirelessly from your computer?

All of my music is ripped from CD into FLAC, and is stored on my local NAS. I use Openelec on the Raspberry Pi 2 to gain access to my music files, as well as Pandora. Openelec plays FLAC files bit perfect. The key component is the HiFiBerry DAC+ Pro. This $50 DAC is made by audiophiles in Switzerland, and connects to the Raspberry Pi top hat connector. The DAC is based on the TI PCM5122 (Burr-Brown) device, which has superb specs. It outputs 2Vrms, and requires no coupling caps. All of this is remotely controlled (including volume) by using one of the many Openelec (Kodi) apps, like Yatse on Android. All of this runs at less than 10w total, and sounds fantastic on my VTA-70. It is completely solid state, with no moving parts, and no noise. Total investment was a little over $125.
