What USB cable are you using now? Im curious to try it again if its as you describe but I was using a cheap Belkin cable so it sounded muddy.
When I went to Gen5 USB, I decided to buy a cable of comparative quality to the AQ Diamond toslink.
My trusted friend Alex at Wywires provided a Wywires Platinum USB cable, 4-ft in length. Similar price to the AQ Diamond.
I believe in upgrading cables. My rig is now all Wywires Platinum cables: USB, interconnects, and HP. Solid quality.
I think way back when (before Gen5), Mike had listed digital connections in order of SQ:
High to low: AES, BNC, RCA, toslink, USB.
Gen5 has moved USB significantly up the list.
I too tried to get BNC input, from the Mac, using a Singxer F-1 (USB2 to RCA/BNC).
It worked OK but another box in the signal path. USB Gen5 solved all that.
