Best USB cable +/- $500

The Synergistic Research Tesla Tricon USB is pretty good.

The Revelation Audio Labs Prophecy Ref DualConduit USB2.0 is a great cable also.

Thank you for your posts. My USB cable search is over. Did quite a bit of research, but in this price range it is impossible for me to audition much as I did in the $100 range.
Ridge Street was a bit too high priced for me. Anyway, bought the Revelation Audio Labs Prophecy Ref Dualconduit USB2.0.
Very, Very impressed with modest breakin it is a big step up from everything I have heard.

I still own the Wireworld Platinum7 and friend has brought over his AQ Diamond, I can say with confidence ,that after exchanging several emails
With Brad the owner designer of Revelation Audio Labs the Prophesy is a excellent digital cable it is actually much cheaper per meter then the other cables mentioned and Quality and care taken totally seperate leggs for dc power ,and for digital and shielding methods and polished 59s Silver
Does make a difference I am hearing instruments in the background
Barely audible with the AQ , or WWorld it does take 200 hours to fully refine but excellent after 75 hours just put on repeat even with amp .preamp off breakin as long as all items digital related are on do a full read a lot of time effort and $$ goes into each cable.i am impressed which is hard to do after 35 years in the field.
