Yeah, Pierre Sprey tends to get a tad hyperbolic in his claims, but I've used his speaker cables, ICs, power cords and tweaks and have been constantly amazed by them. I replaced biwired Kimber 8TC with single strands of Double Helix and the iumprovement in clarity, dynamics and musicality (however you define that) was pretty awesome. My system uses CJ Premier l2s into Gallo Reference Ultimates (I subsequently rewired the Ultimates with Mapleshade wire). Bottom line: you can try them on a moneyback basis. All it costs is the shipping. Good luck, whatever you decide.
