Copper Sleeve over IEC

The Reference models from www.Marantz.com are eliminating /reducing EMI right where it was being generated, the Toroid transformers. The INSIDE images from the website show beautiful craftsmanship of the Reference models and how well the Toroid transformers being covered. Let’s compare them with ones that are “naked” from cheaper MArantz models....

The Halo models from www.ParaSound.com have diff route to reduce EMI. They use thick and solid wall plates to corner up the transformer then move some of the electrical components and wiring that they think would be effect the most to the other side of the plates and away from the transformers.
Other companies may have diff ways to control EMI, but so far I like the way Marantz do theirs most.

Chrissan,
That makes sense, show no harm and doesn't cost much to do. Sounds promising.

Rx8man, I understand what you mean, my Synergistic PowerCell has pretty close plug outlet arrangement too.
Just dont try to fit 2 copper sleeves on the same outlet or next to each other, that will never work.
I was really only concerned with my Cary CD player and Tascam CD recorder. I moved those so they were not next to each other and was able to use the sleeve and plug them in.

Chrissain, not sure if I have the nerve to insert glue inside the Synergistic Hologram D powercord. I may try it first on a lesser (in $$$) cord first. Thanks for the tip.

Nasaman, Marantz seems to have an interest with proper shielding,good for them. Heck,just the fact that they released the video on the copper sleeves shows there on the right track.
Funny though that they didnt provide a ground wire to thier $$$ CD Player...

I'm going to get the copper connectors and give it a try. Sounds very promising!

One question: anybody tried a copper sleeve throughout the whole power cord (for unshielded PC)? I have a stock PC on my Rotel RCD-1072 As you can imagine, it's a cheap, ungrounded PC. So I'm thinking of using some thin-wall copper piping (relatively flevible) + the copper connectors on the ends. And also grounding the chassis like in the Marantz video.

Any thoughts?

Thanks!

Lewinskih01, Personaly, I think most of the improvement is from treating the ends of the digital power cords.

Just for some info, I priced 2" copper I think it was 8 feet long but maybe it was 10.
It cost $88 bucks !!! When your done it will probably bend like Virtual Dynamics cables do...

Perhaps try some copper flashing that they use on roofs.

But hey, give it a go, and let us know how it sounds.

ZU audio does in fact do this on their top power cables, not copper but custom cut aluminum housings. And I believe they are also filled internally with an Epoxy such as mentioned above with filling the IEC with Silicone, because you cannot take them apart even removing the screws so there definitely glued down and feel full not hollow, Zu does this with their RCA connections and XLR as well. They are the quietest I have heard.
