4425 we tested several usb cables including the AQ Diamond with Wireworld Platinum, LH Labs cables, and the Enklein Trek.
The Wireworld was noticably better than the AQ it has deeper bass and was clearer at the same price.
The LH Labs cable was good but not better then the Wireworld.
We just received LH Labs active USB but haven’t given it the thumbs up or down yet.
The Enklein Trek although the most expensive killed every other high end digital cable and it should at $2500. pure silver with propreitary sheilding materials and even the silver pins are directly soldered to the actual usb cable. It sounded like we got almost an octave more deep bass.
You should add the Wireworld Platinum to your list it is one of the best sounding USB at its price point.
I will add haven't tested the Audience yet and with the Wireworld we tested the older series 6 many people don't know that the series 7 Wireworld is dramatically better but it only came out about 1 year ago.
