Dedicated 20 Amp Line for Audio

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???

Well we did it today. The run was 121’ of 8-gauge wire, with another 2 feet to run between the plugs. Seeing as how I had a 125 foot spool of wire, I cut it pretty close!

It is not easy, but not impossible to feed in and jumper the 8-gauge between two hospital plugs in the dual wall box, but using the deep box, we managed.

I also ran RCA panels with six leads from the inside to the outside of the entertainment cabinet to allow me to access various aspects of the system from outside of the cabinet. For example, this would let me bi-amp if I so desired.

Just need to mud a couple slots in the drywall and paint now.
