Don't you just love it when occasionally it all comes together? I have had the cables burning in on the Isotek cd for well over 150 hours. Tonight I put on my best test cd, (Steely Dan "Morph the Cat"...this is a must-have recording by the way and not bad musically either), turned it up LOUD and was rewarded with a wall of clean transparent sound, without a trace of hardness, thunderous bass, extended highs and everything working together like a charm. I don't know if it's the cables or the Jenzen caps finally settling in but I was a happy audio neurotic! I strongly recommend you reserve judgement on these latest Grover's until they have well and truly been thrashed to the last atom. The sound I have tonight it totally and utterly transformed from when I put them in the system. Voila By the way my ICE module amp is a winner. It just sits there, small, cool, and utterly composed no matter what it's asked to do. I had these stone walls pulsing and there wasn't a trace of clipping or strain.
