Having had experience just as Sound 4 me said, I heartily agree. My system was lacking a little-changed my speaker cable and now I think I have the best amp made. Since you do have one of the best amps made, I'd look at the rest of the chain. Good luck.

I had HT cable on my wadia(good),switched to Mamba(light years better). i put the HT on the amp-did'nt work! Everything got kinda dark and a little muddy. I'd try another cord on your amp. I'd also try Analysis Plus speaker cable.
