Dedicated 20 Amp Line for Audio

I've almost finished revising my system with additional lines of #8 wire.

One line is for digital ( CD & DAC ), another for the woofer amps & subs and one line for everything else.

Each AC line has its own dedicated PS Audio power plant. 

A question I would ask is what amp are you using?  Difference between a 8 watt tube and a 500 watt ss can determine if you want to go with 14g

My advice is 12/2 (likely will not hurt your hands) and will cover all amps

RFI is everywhere (if you are on planet Earth that is lol)

If you have 6 open legs in your breaker box make sure your box is not oversized for your line into the house.

I have a very unusual house. Built in 1979, it is some kind of kit that was imported from Canada. It measures 20’ x 40’ with a vaulted ceiling running lengthwise.
The really weird thing about it is it is built-in panels that consist of 5/8" OSB used for the interior walls, floors and ceilings then 3/8" OSB for the exterior sheathing. Then sandwiched in between the 6" walls, floors and ceilings are rigid, styrofoam insulation and glued onto each surface. This was all done as an insulating factor. You can heat the house with a candle!

Most 110V outlets are currently on the floor as it is near impossible to get a wire up the wall from the crawl space. The bottom of the ground sill of the wall sits almost center over the concrete foundation with no room to get a bit at the right angle in there. You have to drill at an angle through the exterior sheathing, outside the house in order to get the right angle down into the crawlspace. Then you drill another hole in the interior wall to line up with where you drilled on the outside the house and fish your wire through that way.

Then comes the fun part, you have to bust out all the white styrofoam. It’s as hard as concrete and sticks to you like glue, it’s a real messy situation. Also, I have found no 2 x 6 studs in the wall so far, just foam!

The idea here is I thought I would save some money and do some of this work myself. Like running in this dedicated line for the stereo system rather than paying an electrician $100 an hour to fight with this. I’m sure they would not be very happy doing this job as well.

Once I figure out what size, type and how many lines to run, I will purchase some wire, run it in, leave them long, and let the electrician terminate them accordingly, once on-site.

That’s all.

lt2917 - #8 wire? Wow!

dseltz - currently (no pun intended) I have a Luxman 507 uXII integrated amp on a layaway plan with a local dealer.
