Copper Sleeve over IEC

2chnlben, Yeah, I thought so too. Jgiacalo, Glad the simple tweak worked for you.

Too bad I didnt put a fancy label and a blue LED on it.
I could have made millions...

Good news Ozzy and tweakers,

Went to Lowes, bought a 1-1/2"x 1-1/4" copper coupler-reducer stock #89479 (smaller end fits closer to the IEC end plugging into component) $3.47 YTMV (your taxes may vary)

Slipped it over the end of the Shunyata King Cobra going to my CEC transport and WOW.

Micro-dynamics, clarity, depth, I'm going FULL-BROKE and buy 4 more (preamp, dac, mono amps ?)

Thanks Ozzy (and Lowes) these could sell for $50.00 a pop and be a deal, price/performance ratio is incredible.

Rx8man, Glad you like it. It really works quite good on digital.
Let me know how it works on your Preamp, Amp.

Rx8man,
Thanks for the tip. I tried but couldn't find the item on their website. Can you send link if not too much to ask?

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
