Copper Sleeve over IEC


There has been several threads on AA about putting a 1 1/2" copper union (coupler) over the IEC on the CD Player, Preamp, Amp.

Well I tried it...

Anyone else give it a try?

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.
