Same mains AC circuit

My AV Preamp is not plugged into the same AC circuit as the Power amp.
Any influence on sound ?
Thanks.

Hi there. It depends on house wiring. Some wall sockets are connected in parallel and some come directly from the fuse box. In first case, probably little to no difference, but in latter case, it may be beneficial (less intermodulation distortion I would think).

The power amp will modulate the AC and affect the sound quality of the preamp. You might consider another circuit or a Power Plant to fix the problem.
