Copper Sleeve over IEC

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.

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)

you lucky so-so Rx8man! I went to Home Depot & Lowes yesterday & NEITHER had any copper couplers larger than 1"! :( I showed them the stock # at Lowes & the fellow came back & said that it did not exist in their system! Where else can I buy a copper coupler? I need atleast 1- 1/4" for the IEC & 1-1/2" for the male AC plug.
Thanx!

Bombaywalla , Man that is too bad. Perhaps you can try on line with a plumbing supply house?

At this place you can get all kinds of copper fittings, including reducers to 1 1/4".

For those ordering I decided to take a Watt gate / marinco IEC and AC plug end to my nearby Ace hardware... Warning NOT ALL THE copper fittings are going to fit, Problem is that ONLY the fittings with a 1.25" ID(Inner Diameter)will work, most of them have a 1.25" OD (outer diameter)

All of the straight fittings I found had only a 1.25" outer diameter so they did not fit over the body of the plug, the 1.5" are WAY too big and you would need to fill the gap with a bunch of tape or something to beef up the connectors size and or Tape it on in place if you don't want it falling off. The best I found was a Coupler made with one end as a 1.25" inner diameter, and it was then reduced to a 1.25" outer diameter… And use a pipe cutter to just cut it at the rounded reducer shoulder and throw the bad half away.. This fits super snug and has a professional finish.
