John,

Jitter as it applies to audio is the clock associated with the data. Since the 48MHZ clock is merly the USB clock and the relaying of data it has nothing to do with the quality of audio since there is no real "clock" associated with the audio data.

In adaptive mode the dac will still be goverened by the computer not the hub.

But a well designed hub could isolate the power from the PC which might be a good thing.

Thanks
Gordon
