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?

Tbg,

It is obvious from the comments that everyone will not have the same results.
Sabai, so what is the probability of success? And who is most likely to have it?
So, I just inserted a thin piece of carbon fiber inside the copper sleeve...
Though I had high hopes for the carbon fiber insert, to me, it was not an improvement.
