I currently own the Shunyata Alpha USB between my Innuos Zen mkIII and Chord Qutest. I use all Shunyata Venom NR power cords, however I use Purist Audio speaker cables and interconnects and absolutely love what they do for my system. The Shunyata Alpha USB has been a wonderful cable as well, but after some recent new additions of Purist Audio interconnects making a huge impression on me, it makes me wonder what the Purist Audio Diamond 30th Anv USB would sound like against the Alpha. Anybody had the opportunity to compare the two?
