Copper Sleeve over IEC

Kenk168, I think they are the same thickness, standard wall.
There is a standard wall, a X-hvy and a XX-heavy wall thickness.
Almost all domestic copper is standard wall.
The thicker walls are used for Industrial use.

The copper couplers are working extremely well in all locations.

My crappier recordings are sounding very listenable, and at loud levels.

This is the most effective, cheapest tweak ever applied to my rig, and I've done many over the years, installing my own IEC inlets, various fuses, damping of chassis, footers and materials etc, etc.

If you do a search for rfi and emi shielding materials you will find many different types and variations. The foil types made of copper with adhesive maybe the most simple to procure and to use. I have a couple of copper foil inductors I could unroll and use for this experiment/purpose. Some slicing and dicing along with some spray adhesive may open this up for some shielding inside of my cd transport. Tom

Tom,

I found a roll of 3 inch adhesive-back copper foil from McMaster Carr,
the inside of my CEC transport looks like a good place to start using it.

Alrighty, finally, I bought 2 of them, 1.5" for my IEC (Note: 1.25" did not fit the Wattage plugs, it just stops right at the black lip of the plug). Paid $4.99/each from Mom&Pop strore since Lowes did not have any copper or brass bigger than 1".
If all materials are getting the same affect then I think next time I will stopby a muffler shop to see I can snatch 1 for free.
I stayed up late till 4:30am last night to test out power cables, and it was so much fun. It was so amazing to see just switching 1 power cable around can change the sound of my music.
Let's see where this tweak will take me tonight... crossing my fingers and hoping for best.
