Sound quality differences between NAS units

[beckphotonik]

I would certainly concur with David's analysis regarding power supplies considering the extreme lengths high end audio manufacturers go to when designing their power supplies. Unfortunately, a NAS (with some exceptions) is still regarded as a computer not audio device where wall wart supplies are quite adequate. Add to this the fact that the human ear is an extremely sensitive organ and can detect minuscule variations in timing and phase, just the factors governing the sound stage experience. I do think that it is a bit flippant to assume that the re-clocking that a renderer performs will eliminate all digitally borne errors so my own view is that the NAS must be regarded as an audio component, and as an audio component, there will be sonic differences between devices.
