Innuos Zenith Mk3 Ultra-low Noise USB Audio Output, Really?

Mega Byte?
I prefer Giga.

MB = Motherboard

Listen to it and see what you think.  Lots of people are thrilled with its sound.  Or just go buy the MB and LPS and build your own and see how that works out for you.  I can buy the same ingredients as Wolfgang Puck — doesn’t mean I can create what he can. 

USB is inherently a compromised interface. That said the Innuos version really is quite accomplished. It does though substantially benefit from galvanic isolation and superior cables.

USB is nothing but unclocked data. Computers do not pay attention to noise only ones and zeros. You guys probably don't remember the old analog cell phones. Needless to say, our modern digital ones were a breath of fresh air. It is all about the clocking and there are any number of great clocks in various formats to do the job. I have not ever had a jitter problem.
