Calvinj, The krell 700cx modified sounds incredible, alot different than before, somehow, the amp has some of the most perfect grainless-none brittle treble I have ever listened to, I am quite happy with the total sound quality over what a normal Krell 700cx sounds like, The Tara labs cobalt that is on the cd-player took a very long time to break-in, longest in my history, I suppose that was due because the digital unit only draws 25 to 30 watts from the wall!, the power cord took 568 hours before it worked out all the quirkes, all that said, I am hearing the Tara Labs Zero Gold do sound that I did not know was possible with this cable, it's like I got a better cable, LOL!, one sound in particular that stands out is the most incredible horn, piano, and vocal music is so organic and real sounding, it makes your hair stand up on your neck, jazz is off the chain, there is a draw back, The amp gets very hot, I have to polish and condition my speakers or the amp litterally dries the wood out in a month, cheers.
