Update (if anyone cares!),
I've run my 3 dedicated lines as follows:
(1) 30 amp circuit breaker/10 gauge stranded THHN/Hubbell 5362IG 20 amp hopsital grade white noise eliminating outlets.
(2) 20 amp circuits with 20 amp circuit breakers/12 gauge stranded THHN/same outlets as above.
All lines housed in an attractive (IMHO) wiremold raceway.
First impressions are noticeably blacker background resulting in greater clarity of the little things in the music (i.e. triangles, bongo drums).
I may still try some of the cry'od Porter Ports.
BTW, I also fabricated some diffusers/absorbers that sit behind my Magnepan 1.6Qr's. These have a light gauge steel tube frame 19" X 65" with 3" convoluted (egg crate) foam on one side only. These have made a tremendous difference in clarifying the sound in my listening area. Less confusion in the top end, deeper soundstage and much more defined bass.
Now as soon as Robert at Ridge Street Audio gets me my cables.......
