Material Specifications/Layout for AC line


Calling Sean, Lak and other informed Audiogoners!! I know that there are all kinds of discussions both current and in the archives regarding dedicated audio ac circuits, but I'd really appreciate some definitive suggestions regarding layout and materials. I know a retired union electrician so I know that I'm in good hands installation-wise. I'd really like some direction regarding layout and material specifications for my system, modest as it may be. Blue Circle 21.1 linestage preamp/Cary 308T cd player/Marantz SA 8260 sacd player/Odyssey Audio Stratos Extreme amp and Magnepan 1.6 QR speakers. I've got some good power cords already (VH Audio Flavor 4, Hot Box and Blue Circle BC 61's).

Thanks in advance.

BTW, I've posted the same question over at AA.

Beatlebum/Tim,

Looks like I might be too late in this thread but I'll put in my 2 cents FWIW:
I used 10AWG romex in-wall wire. After reading a # of threads on A'gon w/ really good info from people like Lak to name just 1 person, by 2nd-hand living what Hbrandt went thru about the same time as I did getting dedicated lines, I decided that boutique in-wall wire was not going to be my pancea hence my choice in romex.
Junction boxes are bakelite & there is no metal conduit carrying the wire to my room => no antenna putting crud on my ground wire! When the electrician was doing the wiring in the main panel, I found that ground & neutral are connected to the same bus! He said that this is normally how it done for homes everywhere in the USA & that only for commercial ops do they separate ground & neutral. I believe that older houses have a water pipe ground connection (which I don't as my house is newer. I must be having a copper-rod-stuck-in-the-Earth ground(?) ).
From Bob Crump's suggestion on AA, I decided to try out romex wire orientation! I found it to make a difference even though it was more on the subtle side. I found that romex run one way had a bigger & deeper soundstage vs. romex run the other way. Of course, this is system dependent so the orientation that works for me might/might not work for you. Anyway, orientation made a diff. for me (contrary to my disbelief when I read Crump's post) & I had the electrician run the wires my preferred way.
The RGPC 400S provides internal parallel AC filtering that benefits my source components & my pre (which doesn't seem to need it as much as Ken S. has put in parallel filtering of his own in the power supply box).
I'm using Pass & Seymour 5362A cryo's outlets from Chris Venhaus with excellent results. The "A" designator in the model # is paramount as that signifies an all-brass Olin #688 construction.
I would have loved to use an isolation xformer like many here are using but the Internal Affairs Secretary @ home would have raised 2 eye-brows @ the cost! W/o the isolation xformer, the cost slipped under her radar! ;-)
