Copper Sleeve over IEC

hi, I am wondering if you grounded the copper sleave . if not it is realy not shielding anything. I bet what you are hearing is michanical dampaning of the iec, which could result in better sound. happy listening, chrissain

hi, i think that it is easy to underestimate the importance of vibration controll on michanical connections. the copper sleave is heavy and dense, and i would bet that a large portion of what you are hearing is michanical dampening of the plug . just a hunch, happy listening, chrissain

one more tweek, for all those of you that can open the iec or male plugs on your powercords, get the clear silicone caulk at home depot and fill your connectors, the improvement is worthwhile . loose and undampend mechanical connections are a source of noise, this is very well documented. see what nelson pass has to say about cables. one more cheap tweak to try, good luck and happy listening ! chrissain
