Hi Jim, sorry, I just got back to this thread, yes, I have been listening, I do have a 10/3 romex connected to a furutech GTX-D Rhodium for my amp, yes, The Krell 700cx amp comes with a captive power cord that says 600 volts rating on it, Jim, I have said over and over, my amp is NOT useing all 30 amps, it simply spikes over 20 amps, all I am saying Jim-Jea48, My krell 700cx runs cooler, more dynamic, bigger sound stage, more or less, effortless useing a 30 amp single pole breaker versus a single pole 20 amp breaker, I was shocked after 20hrs of burn-in of the breaker at the difference this made, Damn Jim, this is the best cheap tweak ever I have done, more than cost effective, I do not know why or how Jim, But I assure you, the 20 amp breaker in my opinon, was chocking my amp!, Thankyou jim for all the post you have done, I really don't have an explaination, I am just telling you that this works, no problems, and was worth doing, and that I know many members of audiogon that did the same here with their Krell amps, I was afraid to do it Jim, Chris Vanhas of vh-audio sold me the furutech GTX-D R with the understanding that it would not heat up or damge the outlet with a 30 amp breaker because of how well it is built, as it turns out, he was correct, not even warm!, I have checked this outlet over and over, the wires going to it, if any smell was coming from it, for heat, nothing, the wpo-wall power outlet is cold all the time with NO issues, thanks jim.
