advice on dedicated line

Thank you, Al. A great explanation that I can understand.

What an education! Thanks, everyone. Even with pros and cons, I confess I am tempted by the simpler route of one 10 gauge 20 amp line with the Porter -port. Would it be workable for me to get 6 outlets instead if 4 in case I ever wanted to plug in a small fm receiver to listen to the news? Or is that pushing my luck?

Also I am assuming that if I just one 20 amp line the points Elizabeth initially raised (circuits on same leg, nothing adding to more than 120) are not things I need to worry about.

In fact, with the single 20 amp line is there anything special I need to tell the electrician other than I want 10 gauge wire, to put the line on the least noisy side of the box, that I want nothing but my audio on this line, and to be careful with the ground wire? Is there anything else I would need to specify?

Thanks again very much. I would be lost without you folks!

For what it's worth I have two 20 amp dedicated lines for my 2 channel system. I ran #10-2 with ground NM-B cable. (Romex is a trade name of NM-B cable). Each run is about 75' each. Digital equipment on one line, analog on the other. My system is dead quiet.

Al, Your last post was right on IMO.

"Solid core Romex has an absolute ton of inductance and you can use that to roll off the digital backwash and end up isolating your analog from digital with yards of the solid core Romex in the walls. Romex is insulated with PVC and, again I will say that PVC is what you want rather than anything faster as you just want to pass 60hz and attenuate anything above that.....Stranded wire, especially a twisted lay, will pass high frequencies better, exactly what you don't want to do with 60hz AC.......

Most of the AC noise/hash on the mains of our audio equipment is connected to is caused by the power supplies of the audio equipment.
Dedicated branch circuits will decouple audio equipment power supplies from one another.

Excellent post Jim. Thanks. That's exactly where I'm heading. I may go for 2 or 3 dedicated Romex circuits. A 15 amp job for my CDP. A 15 or 20 amp line for just the amp, although I suspect 15 amps would be major overkill since the amp pulls about 800 watts (or 7.5+ amps when driving a heavy load). And a 3rd line for the rest of the my gear.

Would it be workable for me to get 6 outlets instead if 4 in case I ever wanted to plug in a small fm receiver to listen to the news? Or is that pushing my luck?

IMO, a better idea is to use a high quality power strip for your low current components and plug your amp into the wall. Then you won't run out of receptacles and you'll be protected.
