Dedicated 20 Amp Line for Audio

Why a "dedicated circuit" when everything gets lumped together upstream of the comnpponent?

Dedicated lines can avoid the noise and voltage drop that may result from daisy chained convenience circuits. It’s a difference you can measure, so it’s silly to debate it.

Many users do both. It's not an either/or choice.

I stepped in some of that the last time I crossed the pasture.  It wasn't hard to scrape off my shoes but left a lingering odor.  

Physics and engineering does not support your claim.

Elimination of daisy chained outlets is huge. Mine was wired that way at first. Of all the things I have done with AC - cryo, 4awg, 240/120 step down - the biggest was the cheapest, eliminating the daisy chain going direct.

Considering this was the first thing I did, way back in the 90's when my system wasn't nearly as transparent and revealing of improvements as today, that is really saying something. 

millercarbon - gotta love those 90’s and pullin’ yer wire! Yes, cryo is good. At one time I was a sales rep for Black Sand Cable and all our power cords were cryo’d, prided ourselves on the fact.

thyce - very informative, thank you, but plug directly in to the wall socket. I presume you have whole house surge protection?

The way I’m reading it so far (Fremer included) is just one dedicated line for audio.

I installed a single 8-gauge, 20-amp line/breaker with the thought that if all of the equipment is on the same source, neutral, and ground, it should be less likely to hum or develop ground loops.

If one were to pull two lines from the two busses, which line would you use to ground a metal outlet box, or would you use both grounds on the box???
