In the "old days" Preamps had switched outlets on the back where you would plug the amps into because the amps did not have a power switch. Some examples from ARC were the SP3A (still one of the best sounding Preamps I have ever heard) and the SP6 etc. So not only was the Amp and Preamp on the same circuit, but the amp was plugged into the Preamp, and I never thought that was detrimental to the sound. Of course that was back in the days before people were sold on $1,000 power cords and $5,000 speaker cables, etc.
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.
