Copper Sleeve over IEC

I have placed the copper union piece at the MarantzSA-11S1 cd player, at the Art Audio Px-25, and at the IEC connection of my PS Audio Premier Power Regenerator. I noticed good results. There is a on going good discussion at the Tweek forum of Audio Asylum of using copper and how it works.. Carbon Fiber Tubes may also work to good effect.
If you buy the copper pieces at Lowes or Home Depoit you can return them for a refund. Cost is about $4.50 each

Ozzy and Tweakers :

I added another copper sleeve on the preamp cord, with an additional increase in dynamics.

A good idea would be to gage the coupler size to your specific power cord end(s) so they are not a sloppy fit.

I might go with 1-1/4" straight across, instead of the reducer from
1-1/2" (provides a closer fit yet)

This is a cheap, awesome tweak, takes seconds to install, is reversible and refundable.

The beauty is, increased musicality with no discernable downsides (in my system)

I'm going to try the other end of each power cord going into the Hydra next.

Kenk,

Lowe's website does not list these specifcally, go to the plumbing dept, look through the bins and size on the barcode sticker.

Ok, you guys got me all hyped up now and I'm gonna give it a shot sometimes this weekend.

- Just for the record, can anyone email me some pictures?

-Do I still get full benefit if my power cord is not shielded.

THanks in advance and the part number is a big help too.

Another update: Add another Copper sleeve to the AC (on the male end) power cord on your CD player.

This sleeve along with the other sleeve over the IEC end of the AC power cord to your CD player really adds dynamics!
Bass is stronger, treble and midrange better defined and smoother and the soundstage becomes more stable.
The best one word to describe this sound is SOLID!

I still have had no luck with the copper sleeves on my Preamp and Amp. With sleeves on this equipment,they sort of suck the life out of the sound. Maybe, because both of these pieces are Pass Labs equipment.Pass may be doing something already inside the equipment that the extra copper sleeves become too much.

But the additional copper Sleeve on the power cord to the CD player is a must!
