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

Chrissain, Why dont you try it for yourself and then you decide?
It will cost less than $5 for one, or under $10 bucks for two.
Try 2 on your power cable to your CD player one on each end.

Rx8man, Try another copper sleeve on your didgital at the Male AC end.

Now I haven't had the time to audibly check what happens after installation but what I can report is that I use a portable AM radio tuned just off a station (to get static) and the polymer or plastic housings on IEC and male ends of my power cords are noisy and do exhibit less noise when the copper is in place. Not dead silent but less noise. I do have 1 power cord whose terminations are finished in aluminium and they are quiet even without the copper on them. One of my cords must not be insulated (its a 3 wire braided cord) which is noisy all along the cord itself so I don't think having copper over the ends will do much but I may be wrong.

While not yet proven by myself my opinion is that this tweak may be most effective on insulated power cords.

Rgd. Actually I'm thinking that the copper sleeve at the ends is the only place shielding is important.
If you can eliminate the nasties going into your components they will have less garbage to work with.
