Copper Sleeve over IEC

Ozzy, I tried this about four years ago. I gave up but have since used my meter to assess leakage. I have none.

Ozzy,

I'm getting a nice improvement on my DAC and transport.

Ozzy, Thank you very much for this tweak. Bought several from Lowes Hardware and Wow. Smoother more relaxed sound, without sacrificing detail and even improved overall soundstage a little. Used on iec at power cond. ,both ends of CD power cord , power supply of pre-amp, and iec of phono pre-amp. Also opening and closing your CD tray twice before playing made a significant difference (apparently improves reading of disc).

Swinfrey, Sometimes too many of them will dull the sound. But, do try them everywhere.

Great results with a single Super Sleeve!

I "stretched " a 3.25" copper sleeve so that it became
oval.  It could now encircle both plugs on a single
wall outlet.

One plug on a dedicated line (SR black outlet) contains the cord
to a SR Powercell 12 and a High Fidelity 0.5 magnetic wave guide.
I used 3 small cork rectangles: one in between the plugs
and the others between the plugs and the body of
the sleeve (top and bottom).   There is an additional sleeve over the SR cord, that is easily fitting inside the Super Sleeve.

I recently treated the wires of the outlet with Total Contact,
and applied it to the face of the outlet, and the outlet cover.

I am hearing a more relaxed, natural presentation
of music, with no fatigue.  Highly recommended.
