Choice of Wire for Dedicated Line

William, in my opinion there's a lot of RF everywhere. But obviously a bit more in your local.

To me, the advice is the same. I would recommend a 10guage 99.95% OFC that you can pick relatively cheap at partsexpress.com or some similar site.

Then to address the RF and general noise on the AC lines, I would recommend some type of power conditioner.

In my case, I'm using Foundation Research LC-1 and LC-2 dedicated in-line power conditioners that actually take the place of the power cord and cost about the same as a good power cord. Yet, the LC's do much more than power cord in the way of cleaning up the electrical noise.

Hope this helps.

What ever kind of wire you get it should be shielded... the shielding is what will protect it from the RF. You can get regular household wire 12-2 w/ground for example in a metal shielded version.

A couple of other ideas (assuming you are not going to a higher end audiophile cable that is very expensive), depending on the length of your run you should probably run an extra line at the same time for your Gonzo Krell or ARC amps. Or you can run 12-3 w/ground (for 20 amp service) and use the red line for a second dedicated outlet, eliminating the need for a complete second cable. Also, you should drain to ground the shielding on the cable to further eliminate RF.

Then if you need it, consider conditioning.

I was talking with a guy I know that owns a company that makes power cables about this subject and he recommened steel-shielded BX cable, or at least I think that is what he said he uses for his own lines.
