Copper Sleeve over IEC

I have looked at the forum site where this tweak was first reported. I was interested in the idea of outlet cover material improving the sound. From what I read, brass outlet covers did not make a difference, but carbon fiber added to a plastic cover or the expensive commercial covers did make a small improvement.

David my last post was in reference to removing the entire cover off the AC mains breaker box. Tom

Chrissan,
I just talked to 1 electrical engineering at my work and, just like you brought it up earlier, he too rec'd to run a ground wire from a coupler to the classis. Verified.
He thinks to design a "metal hat" like Marantz do to their REference lines to shield up the entire transformer is not a bad idea...

Brought my EIC connector in local Ace hardware for sizing but their biggest size avail. for copper coupler was half inch or 3/8". Does any one have the part number from Lowes of Home Depot?

Nasaman,

Lowe's is a better bet, even though I found their bins a complete mess.

#222144 corresponds to a 1-1/2" coupler.

Bring your cord and get the size that fits closest, you may need 1-1/4" so
read the label on the coupler to verify.
