Kana813 - the SMPS that drives the SB3 definitely has an effect on its output jitter. This is independent of the PC power supply though. I suppose if you wired the SB3 to your network rather than using WiFi, this might add ground-loops that would introduce more noise?
I'm saying that PC-audio CAN be affected by PC power supply and ground noise, but it's not necessarily the case. Depends entirely on the USB converter design if it's USB. If it's networked, then the answer is no, it is not affected by the PC in any way.
I use the SB3 and Sonos wirelessly and feed them through a Pace-Car reclocker. This totally isolates everything: the clocks, the ground and the data signals. In this case the jitter is not a function of the PC, the SB3 or the Sonos, only the clock in the Pace-Car.
