Please advise re dedicated circuit

Considering doing this. I mean, having an electrician or myself install a new circuit with one or two outlets for the audio system. When I finished my basement last year I did all my own wiring after consulting with a helpful chap at Home Depot so I could maybe handle it myself.

First, is it always an improvement? Some of the threads here talk about it being less than desirable if using stock PCs, which I will be doing only for my CD source - a Sony C555ES which I like very much for its changer capability and the sound is pretty good too. I might consider switching out the captive cord and getting a plug installed but I'd rather not risk the warranty loss - 5 years with ES products.

Anyway, should I use 10 gauge? And, if getting an electrician to do the job, what kind of cost should I expect? I know, it depends, but looking for a *range* here... about 70 feet or less of pretty much straight run, suspended ceiling to work through, so it should not be too complicated.

Would like to hear your experiences!

Thanks, I might try it. May hit a snag with the baseboard, though. Went under and looked for the existing outlet, could not see the wires leading to it, which means they are above the subfloor (of course they are!) I was actually thinking of replacing this outlet but now I think maybe a brand new one is the way to go, may be simpler.
Question: if doing two, is it a compromise to splice the second off the first? Yes I know the argument is for dedicated, but I would still be using only two boxes, both only for audio (and maybe video). Actually, with just the CDP and integrated amp to worry about on the audio side, maybe I just need one... but good to have two in case...

Compromise-not much I think. I installed one, then added another at a later date. I have a monster 7 channel amp and the books strongly recommends a dedicated 20 just for itself(I think they are blowing smoke).

The main reasons if to separate analog front digital. I don't think your into analog. Also I like to keep subs on a different line since they tend to be "noisy".

Also the whole point really is to reduce the number of connections. If you do run two outlets from one line, have the first outlet by your main gear.

There are a lot of threads talking about dedicated circuits/10 gauge/12 gauge/15 amp/ 20 amp.

There seems to be a consensus for running 10 gauge to a 20 amp dedicated circuit. The more, the better.

KCK: At 70 feet, you should be running 10 gauge at the minimum. Don't know the size of your amp or current draw, but the longer the run, the more voltage drop you'll have under load. Since it only costs a bit more for the 10 gauge versus the 12 gauge, use the heavier stuff right off the bat and be done with it. Even if you don't pull that much juice from the wall, you'll have peace of mind knowing that you are well covered, even for future use.

Marty: The "little" two channel Sunfire amp ( 300 @ 8 / 600 @ 4 ) can pop a 15 amp breaker if your standing on the volume with a 2 ohm load. As such, trying to drive SEVEN channels with a big amp and inefficient, low impedance speakers could be a real handful for anything less than an ideal AC circuit. Sean

Sean: I guess in my experiences I've used speakers with >88db sensitivity and >4 ohms. I know(the theory) the current requirements go up in a steep curve as either/both these figures go down.

I'll have to try something different and see if I can shoot flames across the room....:)
