Curious Evolved, JCAT Signature and iFi Gemini were all great with the edge goint to JCAT for me, but I'm still in AES land. Likely moving back towards USB needs and curious about the Inakustic and if anyone's tried Snake River's USB (his Boomslang AES is fantastic). 

These USB's seemed to be responsive to galvanic isolation gizmos from iFi - Loesch is generally a solid designer to my mind and ear. I tend to not like so many cables and boxes, but they seemed to round the leading edges in a way my sensitive old man ears appreciated.

Oh yeah, the FTA Callisto - a little soft even for me....

Supra for a long 5M run:

I am considering upgrading my digital USB cable. Reading this thread has been informative but also seems like there are so many choices out there, and what cables do what is sort of unclear to me.

Has anyone tried this one? This seller seems to advertise on the used sites a good bit.  I think I would like to stay in the expensive but not crazy price of say a couple hundred bucks max.

Avanti Audio USB

Sablon 2020 USB replaced a few in my system the were much more costly.
