In Reply to: By the same principle, shouldn't wireless ethernet be superior to wired ethernet? posted by Boybees on March 20, 2006 at 16:07:51:
Yes and no (of course there is no simple answer!) The USB devices are fairly susceptible to noise on the interface because they are still running adaptive mode where the jitter of the recovered clock is fairly tightly coupled to the incoming signal. An ethernet stream does not do this at all, the clock going to the DAC is highly DE-coupled from whats going on in the bus, this is one of the BIG advantages for ethernet interfaces right now. (which nobody in the audiophile world is really taking best advantage of yet) In most ethernet implementations today the signals go through transformers which DOES mean the devices are isolated from ground connections, but some jitter causing noise can still get through (I'm NOT spending the time right now to go into THAT)Yes the wireless connection gets rid of the residual jitter effects from the wired connection, BUT you wind up with a RADIO in your circuit that is generating it own frequencies and noise effects. All in all I think the effects of the radio are worse than that of the direct connect, but both of them are MUCH lower order effects than what is happening in USB audio today.
