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?

Also, after today experiment,I want to confirm that this copper tweak WILL NOT work on Ayre D1xe DVD player. The video will be blacked-out. Confirmed.
Note: Ayre D1-xe equipt with seperate power supply.
Same as Ozzy, too much was not a good thing for my system either.

The tweak worked awesome with my CD player (or what I'm using as a CD Player, PS 1), and my Oppo 980 DVD player, improved, but to a lesser extent, my DAC, but killed the sonics on my tube integraed (PrimaLuna PL2).

I have an aftermarket PC on my amp and stock cords on my other gear (don't know if that makes a difference).

I also have the couplers on both ends of the digital gear.

On the amp, it flattened voices and made the high frequencies "tizzy".. I only had the coupler on the female/amp end but it was a very noticeable degradation of sound.

Either way, great tweak.. best $2.39 CDN I've ever spent. I can't believed it worked.

I also make a little sleeve with Duct tape around a little bubble wrap to create a snug fit and have the couplers tight up against the chassis..

Wondering if it puttin a coupler on my cheap power conditioner would make a difference?
Wow, with this copper sleeve, the video is also greatly improved, too. Not just more colorful but clearly details as well... Speechless!
"Out Sourced" movie is a great one for testing sound and video. Grab one!!!
Nasaman, Quite honestly I saw the biggest advance in Video with the tweak.. Audio about 5 to 10% maybe, video 15 to 20% cleaner. For the most part as stated above this is most effective on digital gear, however more so on the transport side even over a DAC.

RE: Enhanced Video

Did you place the copper sleeve on the DVD player/transport only, or did you also place one the TV AC cable?

Also, what's the consensus on diameter, 1 1/4" or 1 1/2", and if you were to place some adhesive-backed poly foam (like a weather stripping) inside the copper sleeve to help hold it in place, would that have any negative impact on the enhancement (i.e.: dielectric problems)?
