One problem with assessing a music server is not only the quality of the output but also the input quality of the DAC (+ cables etc.) are important. The Zenith has USB and ethernet out and for my DAC(-amp) a Devialet Pro ethernet is presently considered the better option next to AES (the opinion of dealers and my own experience). But presently my unit gets upgraded with a new server/Wifi/ethernet /USB board and the inputs supposed to be improved. I asked Innous and they stated that likely USB will be better. So I will have to experiment with both connection types but I wonder how much the quality of cables will be confusing the decision making process between USB and ethernet.
