My recent USB experiments involved Clarus Crimson, Crystal Cable Diamond, Audience Frontrow, Pink Faun, Veritas Audax, and a Chord Company Shawline.
I liked the Veritas Cables Audax and the Pink Faun USB better than all the rest, with the Veritas giving by far the most value for money. The Audience was also very good. After that it was Clarus, Chord, then Crystal Cable, in that order.
Probably with different gear I may have come to some different conclusions. But I suspect my top 3 would remain even if they maybe switched order a little.
