Wire World Platinum and never look back! It will set you back about $600. Joe, usb cables are system dependent as are all cables. You may or may not hear a difference. It probably has to do with the usb implementation and power supply on your DAC.
We did a shoot out of cables in my system last year. We used a WW Platinum and Lightspeed both $600 cables, a WW Starlight Red 7 and a cheap Pangea cable. They sounded dramatically different. the WWP sounded the best with the Red coming in second. The LS next but it was way too bright sounding. However, it had the most detail and resolution. The Pangea sounded too bright, weak and thin without any depth.
The WWP was detailed, smooth, neutral and natural sounding. The WW Red however, sounded veiled in comparison and was warmer and darker.
Interestingly, when we used my Regen, it greatly closed the gap between the WWP and Red. The Red lost its veil and had more detail but still had just a hint of warmth and darkness. The LS still sounded bright but less so and there was no help for the Pangea although the sound did improve some.
Another interesting fact is that the guy that owns the WWP and LS prefers the LS in his system with a Hugo Chord and T+A DAC8. The LS does not sound bright in his system. Go figure.
My advice, rent different USB cables from the
www.cableco.com and see what you like. You can take home up to 5 cables with a deposit.
