Copper Sleeve over IEC


There has been several threads on AA about putting a 1 1/2" copper union (coupler) over the IEC on the CD Player, Preamp, Amp.

Well I tried it...

Anyone else give it a try?

I've tried the Stillpoints ERS cloth wrapped around various IEC's in my equipment, serves same function. Sometimes beneficial, other times deadens the sound, not using any in present setup.
Where's the YouTube video ?
