Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: The USB cable is on the DAC's INPUT....

"Are you really saying that you would expect 'noise' on a DAC's USB input to show up after digital to analog conversion as measurable 'noise' on the DAC's analog output?"

Well yes, or no, based on many factors. Noise amplitude, frequency spectrum. Internal DAC PCB layout. Analog circuit design factors. Power supply bypassing effectiveness. Internal shielding. Grounding scheme.

All these things. But I do think this is mostly a theoretical problem. I personally think a lot of this conducted noise and jitter FUD is made up to sell expensive USB and SPDIF cables.
