Has anyone tried the Shunyata Diamondback PC?

Anyone have experience with this cable in their audio system?

Thanks!

Thanks to all who have responded..

I have heard these cords serve well in video applications, even my dealer suggested I try them on my plasma, (that's not the response I was seeking). Anyway, as the cables continue to break in they are sounding better, but as noted above they are a bit forward and lack dynamics. Maybe more break-in time? I have around 150 hours on them and was told I should put on at least 300 hours before critical assessment. Any additional thoughts would be most welcome.

In my system I tried the Diamondbacks and was not impressed and I gave the cable about 300 hours of break-in. First, though they may have their merits, the connectors were average at best. I tried other cables fro big names and found the Nordost Magus to outperform the Diamondbacks by a significant margin and their about the same price. In fact, I was so taken by the Magus I fitted most of my system with it. At it's price point give the Magus a try, you will be surprised. One issue with the Magus is it takes about 500 hours for total break-in. A source of the Magus is Scott the cable guy, he burns in the cable on a device that delivers you the cable broken-in. Music Direct also sells the Magus.
