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!

@danmar123 it was great. I only upgraded because of a good multi-component trade opportunity. I think, but wouldn't swear on it under oath, that the N20 creates a slightly quieter background, but the effect is not dramatic. The sound quality of the N200/aero pair was entirely natural, dynamic and captivating.  I doubt you’d be disappointed.  

@kirkwallace didn’t realize Aero doesn’t have AES, but with the coax connection you’re good - same clock priority.

I just missed one.(n200), hope by the end of the week I'll hear from another seller if he except s my offer.
