Amp and preamp on same outlet?


Just how much of a no-no is this? ARC goes as far to print in their manual to say to have the amp and preamp on their own circuit. I live in an apt. and I'm forced to have both plugged into the same outlet. Cords just don't reach....How much sound quality is lost by doing this? It sounds great as is, but is there a major detriment to this? I'm curious.

Jim, science is not all!, I am telling you, please listen, My amp does not get hot any more, got a bigger sound stage, runs smoother, hugely more dynamic, Jim, how do you explain why a single pole 30 amp breaker did all this when a 20 amp breaker choked the crap put of my amp in every way?, also Jim, this is very incredibly noticeable of the difference between the 20 amp and 30 amp breaker on my amp,I also have a $240.00 top of the line furutech GTX-D Rhodium for an outlet with the breaker, works safly, the outlet is cold all the time, period.
Jea48, I do not understand why you would make humor of the truth, I had numerous others with the Krell 750MCX mono block's and the stereo Krell 700cx say the same thing, they encouraged me to use the 30 amp breaker as did krell them selfs,no one knows it all, we all learn from each other, I did not believe that the 30 amp breaker would do any thing either, but when I got 20hrs of break-in on the breaker, it turned out to be the best cheap tweak ever I have done in my life time, the benefit's was worth thousand's of dollar's to me!

Jim, you do not understand, Krell runs 30 amp braker on every krell 700cx, 750mcx amp there at the factory, BTW, I have 4 fuses, well with-in the current capability useing a 30 amp breaker, as I said befor, I am not useing all the 30 amps!,however, This amp in particular spikes well above 20 amps while in use, maybe you should call krell, then you will get all the theory as to why this works properly you want, remeber, this amp at full power is 6,000 watts!
