AC Power Question


I am repositioning my system and need to install ac outlets. I assume its a good idea to have a dedicated circuit for my system below ( stereo only). Should i have 2 dedicated circuits? 15 or 20 amps? I may also have a power conditioner in the loop as well. Thanks in advance for any thoughts and advice on do's and don'ts....

The cost difference assuming you have the breaker space for it is almost zero, so go for 2 x 20.  This requires only 1 more conductor.

You can underrate, which is a little safer. Choose 15 A breakers, but 12 gauge wiring. You get the low resistance of the thicker copper, but the safety of the lower tripping point.

Also, you may need a cable TV ground isolator. Might as well get one, they're cheap and prevent ground loop issues later.
Correct me if I'm wrong but if using two runs off two breakers, make sure they are on the same phase or you could get noise. I used 8 gauge on a 20amp breaker.

"if using two runs off two breakers, make sure they are on the same phase or you could get noise"

That is myth, fiction, and misinformation there is no truth, validity, or basis for this claim where do you think the "noise" will come from!
