  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?

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
