Dedicated 20 Amp Line for Audio

Lots of threads on the subject already, but I’m a little confused on one thing. Is the dedicated line just for the amplifier (in my case an integrated) and another line for the other components? Or, is it just one line for everything in the complete audio system?

Thanks!

I would run at least two dedicated 20 amp lines for audio. IMO, amps should be on their own dedicated 10 gauge ac line, nothing else on that line.

@high-amp,

IMHO, I would run a 10/AWG BX/MC cable with solid copper core conductors from the breaker panel to a metal receptacle box. The metal sheathing on the BX/MC cable absorbs the (EF)) electric fields emitted by the wires and shunts it to ground. Now from panel to plug is shielded. The upside is low line noise and reduced antenna effect on AC power lines/branch circuits.
Downside BX/MC cable is pricier. I would run at least two dedicated 20 amp lines for audio. I have four in my audio rig. All four dedicated audio circuits are 250 volts 20 amps. With no noise or ground loops. Also, all four dedicated audio circuits are at the top of the breaker panel numbers 1-8. See the links below. Hope that helps.
