USB cables conducor - help

@lalitk gives a good suggestion there. Back when I was using my Mac Mini as a streamer I used the The Wyre4Sound USB Reclocker between it and my DAC

It did help a little.

@lalitk is correct

Another strong vote for streamer first.  iFi Zen stream at $399 offers a lot of sound quality for the $$$ and not a bad way to start, then worry about a better USB cable.
