Also Audioquest's jitterbug should be available soon. If that one would be of similar benefit I would prefer it because of its tiny size (and price).
The Regen does impedance matching, cuts the 5V from the PC and injects clean 5V power and it regenerates the USB signal (using an active USB hub IC) using clean and precisely regulated power and a good quality oscillator/'clock'.
The TotalDAC D1 cable has a built in passive filter.
I own both and yes they complement each other, though I myself haven't tested with a different USB cable (not going to as well) I've seen this reported by others. Even two Regens in series helps to improve performance.
The AQ jitterbug is "merely" a USB data and power filter so I don't think you can compare it to the Regen.
So your assumption is that passive filters like Totaldac or may be Audioquest (obviously presently unknown) perform similar tasks? Also why Devialet needs clean 5V from USB? I tried some experiments with and with out USB power from my macbook to my D250. It needs the power connections to do the " hand shake" to initialize the connection but afterwards one could cut that connection. I do not know which side of that connection really needs that hand shake. I surmise that reclocking could be the major improvement to any computer based audio!
