Dedicated power circuits

I’m having some electrical work done including a whole house

generator, surge suppressor, and a new panel box. I am also going to have two dedicated power lines run for my stereo. I’ve read a lot on here about how this is a really nice upgrade and would greatly appreciate any advice to help me along on my project. Right now the plan is two 20 amp circuits with 10 gauge wire. One for my amp and one for my preamp and sources. My equipment is a McIntosh MC 452, a C47 right now but a C22 in the future, Rega P8, Rose hifi 150b,  McIntosh MR 74 tuner and Aerial 7t speakers. I’m also replacing my panel box with a new one. It’s a brand from a company that’s out of business and the quality and safety is suspect plus there are no new breakers available.

 

So starting with the breakers, then the wire and finally the receptacles what should I be looking for? The electrician that just left here is planning on the new panel being a Cutler Hammer brand. Any help would be greatly appreciated.

Agree with the idea that getting rid of differential noise is best done with an isolation transformer rather than relying on AC cable twists.

One interesting article I read a long time ago suggested that a significant benefit of armored cable in general, including bare-armored-ground (BAG), was that lightning surges were carried better by the armor than the ground conductor inside due to actual skin-effect issues with high frequency strikes.  The armor seems to have performed as a very low inductance path. Can't say I noticed a big improvement in noise when I used it though.

Wiring an AV room is not the same as wiring a 2 channel audio room. 

+1, I am wiring two top height channels with AQ speaker wire this week after moving them. more wires, more ways to screw up. This is like "wire surgery", careful matching of connections, wires, amps, and speakers.

Well, I typed for 1/2 an hour then stepped away and it all disappeared.

No offense, but I rely on Chubby Checker for doing the twist. LOL 😁

Grrrr.  Should have written common mode noise.
