To the OP @sbank Spencer: I no longer use USB cables, but when I did, my favorites were these two:
1) Synergistic Atmosphere X Reference (about $1,000 retail): https://www.thecableco.com/cables/usb-cable/atmosphere-x-reference-usb-cable-8099.html
2) Sonore USB cable made to order by Cardas: https://sonore.us/USB.html
This is sleeper. Right below $1,000, but it sounds amazing. Not many in circulation, so it would be hard to find used.
