Copper Sleeve over IEC

Tried the sleeve last night and was astounded at the improvement just as Ozzy described. More articulate bass, more precise imaging and deeper soundstage. Gotta get one for my HT/secondary system now.
Thanks for the great suggestion!

Interesting video, which shows the application of multiple tweaks (not just the copper sleeve). Have you tried using a homemade ground wire as seen in the video? It looks as if he used a regular 3-pin plug, but removed the positive and neutral pins – leaving only the ground pin; then he simply screwed the other end (bare wire) to the back of the CD player. Additionally, he noted that you should load each CD twice before playback. Anyone try all three of these tweaks in combination as seen on the video?

My CD player already has a 3 prong outlet, so I havent tried that suggestion.
Nor have I tried the double reading trick, although that one is easy to do anytime.

I guess I didn't catch the fact that the Marantz did not already utilize a grounded connection - I thought the tweak was in addition to... Strange that a highend unit like that doesn't utilze a grounded connection.

2chnlben, Yeah, I thought so too. Jgiacalo, Glad the simple tweak worked for you.

Too bad I didnt put a fancy label and a blue LED on it.
I could have made millions...
