USB cable recommendations

I recently purchased the Bricasti M3 for my system & am looking to upgrade my A-B USB cable. I currently have 2 USB cables that I used with my prior DAC (Qutest), a Cardas Clear that I preferred with my Qutest & an XLO ultra plus that I far prefer with my M3. It is OCC copper & actually sounds very good, but wondering if I can do better. 
My target price is around $500 used, certainly willing to do less & willing to do more for the ’right’ cable. I am looking for a cable that is absolutely neutral.
I actually tried to buy an AQ diamond used yesterday, but was 2 hours late. Not sure if it was the right choice, but it was a great price & could resell if not right.

My virtual system is available, but my digital side is: Aurender N150 > XLO ultra+ > Bricasti M3 > Zavfino Arcadia > PSAudio BHK w/tele medical NOS tubes > Zavfino Fusion mk2 > SimAudio Moon 330A > Transparent + gen 5 > KEF Reference 3’s.

Please let me know your thoughts and/or recommendations. Thanks!
