“USB audio, an interface that should intrinsically be plus-n-play, seem to be fraught with problems. For some, the iFi Audio micro iUSB3.0 is a controversial device. Enjoy the Music.com reviewer Clive Meakins feels it is not controversial at all. Yes USB is wonderful for transferring files to a printer and I don’t see people saying that files are corrupted when transferred over USB, but playing music is not like printing a document. There is scope for electrically noisy computers infecting the ground plane of the downstream DAC, not only is the ground noisy but the +5V supply will be quite unpleasant too. Noise on the DAC ground plane may not impact the digital section of the DAC but DACs have an analogue section too; this is not somewhere we want to inject noise. Even if your DAC is not USB powered or does not use USB power for its USB card, there’s a good chance the DAC ground will still connect with the USB ground.”
Thank you Clive, Steven and Enjoy the Music! |
