USB cable opinions

If you try a Purist USB cable it needs to be the 30th Anniversary not the Ultimate.

Audience +1. I prefer it over WW and a few other brands that I tried on my system. 

Antipodes DX Gen 2 here and using Totaldac USB Cable/filter into W4S Recovery with outboard LPS then Curious Link into Metrum Pavane Level 3.  Sound good to me but l haven't used the other cables being discussed here.  The Totaldac USB is preferred over a full Curious Cable USB set-up for being a little more accurate and resolving without losing tone and musicality.

I don't think they make any difference, and that is to be expected. See here for some telling tests: http://archimago.blogspot.nl/2013/04/measurements-usb-cables-for-dacs.html

+1 Audience.  I switched from the Wireworld Platinum USB cable to the Audience AU24 SE USB Dual End cable and it sounded much better.  I immediately heard better bass, clarity, less noise and better separation. 

Th Audience USB duel end cable is excellent and I recommend it.  If possible, you should audition some of these cables so you can best decide.
