Copper Sleeve over IEC

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!

Ozzy,

I put copper sleeves on the IEC ends for the transport, dac, preamp,
mono amps & twist-lock P/C to the Hydra, the sound in my rig is fabulous.

This tweak did much more of an improvement than changing tubes or power cords, about a good 15%-18% total for less than $30.00 !

Rx8man,
Glad to hear the tweak is working out for you.
One question, what brand are your power cables and are they shielded?

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.
