Copper Sleeve over IEC

I use brass ac outlet cover faceplates. My power cords use steel bearing fill as a dielectric RFI shield as well as being a drain for micro-vibrations. I love that sound. I will try out the copper end shield over and near the IEC end of my power cords. As I described my power cords shielded construction, would not both ends unprotected as they are, be improved with the copper shields? I hope to find out soon. Thanks for the tip. Tom

Ozzy, Thanks a lot for the website links. Indeed it was too bad @ the local home improvement stores.

Undertow, thanks for the detailed explanation - looks like a 1-3/8" reducer to 1-1/4" will do the job. I do have a local ACE hardware store that I can try. I will take my IEC along.

Rx8man, thanks for your kind words re. the Scintillas! They sound as good as they look but need a brute of an amp to do the job. These speakers belong in the "Society for Cruelty to Amplifiers"!! ;)
Yes, I did discover McMaster-Carr. If my local ACE store does not work out, I'll order online. Thanks for the M-C suggestion.

Undertow,

Blu-Tack's a GREAT idea to take up the excess I.D. and damp.

I'm doing that on the 2 stock P/C's to the amps, thanks for the tip !

Remember when trying the copper too much can be a bad thing. It improved my Marantz SA-11S1 using copper at both ends. For my Art Audio Px-25 amp, copper helped at the IEC end but additional copper at the male end collapsed the sound stage. Both cords go to a PS Audio Power regenerator and not directly to the wall. I bet it will help most CD players as they generate a lot of noise to the A/C line. I think the improvement to amps will vary.
Have fun experimenting.

Yeah the blu tack is perfect for this application and semi-permanent, and has better mechanical and damping properties as well. Plus leaves no residue on the copper or your plugs which is nice, so you can test this out where you want and reverse it quickly. I also have decided to only do the IEC ends on my amps, and Do both ends on my DAC and Both ends on my Transport… Mainly I stay away from preamps with this kinda thing as it does seem to suck some life out of them.. Most analog gear accept amps for that matter don’t seem to benefit from this, such as phono stages etc.. I just do the digital fully and the amps just the IEC connection.

I am curious however if there would be some benefit adding a Drain wire by soldering a small wire onto the Copper coupler at the IEC end and connecting it to the back of the Component chassis screw with a quick conneect tab or alligator clip? It would be grounded this way as well, not sure if any benefit but interesting. This way you have a positive solid connection as it seems in the marantz video above he basically was just trying to hang the copper so to touch the IEC inlet screws…

I can see however its worth using stainless steel or Brass wall plates for more isolation on that end vs. cheap plastic ones.. However I would not pay the 30 to 300 dollars for the voodoo carbon fiber or brass plates from some of these guys advertising them!
