Building a Power Strip, any advise?

Four 12 gauge wires in a quad twist. thus two wires are for hot, two wires are for neutral. Those just fit into the aftermarket A/C plug (with one of the two additional grounds)
Two quads, and two wall plugs into the A/C duplex in the wall.
The run of wires is bundled so the two quads have the extra ground wires between them
The far ends at to common plastic A/C boxes. One box has the duplex split so the quad pair entering it have one pair for each half of that duplex outlet.
The other quad is split aat the end so each pair goes to it's own double duplex box a further 10 feet down from the first single box.
(So each end of the rack area has some power outlets)
One conditioner is on each of a quad. the others are spares.
The in wall duplex I added a real jumper of the same wire instead of just relying on the internal metal link between outlet pairs

I just purchased a Oyaide R1 outlet. So when I build the power strip I will use;

*Audience Cyroed,
*Maestro,
*Oyaide R1
*Synergistic Teslaplex.
Still waiting for many of the parts.

A few helpful hints.

Use the silver plated wire on the positive and neutral post, not on the ground. Use a quality 10 or 12awg pure Copper cable there. This will neutralize any excessive brightness coming from the two silver plated copper cables, and add more fullness and smoothness to the power strip.

Twist the two silver plated cables together, and counter spiral wrap (not to tight) the pure copper ground cable in the other direction. This helps with EMI and RFI interference.

Use your own Copper Sleeve tweak on the power strip. Put the copper sleeve at the base where the power cord or IEC goes into the unit. I have three DIY Power strips made this way in my system now.

Ivan_nosnibor very detailed post about all AC outlet's ringing is true. So when I made my power strips a couple of years ago I started trying different things to stop the ringing. I ended up with copper faceplates on all my outlets and I used Carbon Fiber peel and stick strips on the faceplates. Just a little on the sides and top. To much and the sound was choked. Removing a piece less than a 1/2 inch was the difference. You want to calm the vibrations and not take away from the music. It looks like a fun project, enjoy.

Jejaudio, Thank you for tips, I will use them.

Jejaudio , By the way, where did you buy the carbon fiber "peel and stick" ?

Does anyone think that using some ERS within the power strip to be a good idea?
