The idea started after reading this thread about low power consumption setup:
Apparently this little puppy will boot Ubuntu 10.04 Linux for $74 shipped:
Linux support for hiFace 2 mentioned here:
Basically we should be able to get a portable rig going after we have confirmed that hiFace 2 is indeed compatible with MK802 running Ubuntu 10.04 Linux. Then connect the digital output of hiFace 2 to portable DAC from iBasso or RSA etc.
After that, use a smartphone or tablet as remote control:
Sound quality should be relatively nice for the money.
Full size USB port of MK802 should have USB host function enabled so even USB DACs might work with Ubuntu:
Any comments from (potential) owners of M2Tech hiFace 2 here?
