20amp cord

the Previous Post may be not clear enough.
All Power conditioners, RGPC, CSE sine_wave Reformer, Power Cell of Synergistic Research, work with less merit increase
in the inferior set, though the environment actually need
more of them. all or any of them proved to be of effect
( extent varying due to position they are used in the system ) more in the more advanced system, though the very front A/C power are already isolated .
One experiment, a little wasteful with 6-socket RGPC 600's
is where I put it in-between the CSE sine-wave reformer & the CD ( the former deliverying max only 1K WATT, which I aimed to used only for the WADIA 861 CD ) it also show dramatically improvement to the source CD.
But most of the time, I used now
for the HD TV, Blue-Ray DVD, the DAC separately for the DVD
since I enjoy the improvement to TV video signal most out
of the RGPC. and also separating two dedicated A/C - Video and audio Portion .
For Sound Quality, the ER Power Cell then
CSE Power reformer works very well for the other gears.

For head-to-head compariaon, may be personalised /biased any how, and not withstanding the price difference, for pre-amp & Power amp
works better with SR Power Cell than the RGPC ( which one must be reminded that RGPC is only 1/3 of the pirce )

The RPG is basically a 6 henry choke connected across the incoming power line. As such, the choke conducts very little current and that is why the choke wire only needs to be 18 guage. That also explains why this unit can have an effect on a circut even if the components on that circut are not plugged into it. So, what I am saying is don't be concerned about plugging equipment into it because of the wire size.
I have used the RPG 400s with success in certain situations and like other components, you need to try it and let your ears be the determining factor. If you don't believe it helps your audio, try it on your video circuit. For some reason, it seems to be easier to "see" the differences than "hear" them.

When I sold the Grays the rep said plug your gear into the wall not the Gray, especially if you have a high power amp or anything else that draws a lot of current.

I second the opinion about direct wall-plug use for the amp. A-B it, and I think you'll agree. I know I was very surprised.

DIY solid core min 13awg pc`s direct in-wall.
If then your equipment had solid in-box powercables too..
