Copper Sleeve over IEC

I have had great response using Wright's Anti-Tarnish Silver Polish.
First, I cleaned all metal surfaces on interconnects and power cords.
I used a q-tip and couldn't believe the dirt that came off.
A smooth cloth was used to buff each end.

The sound is great. Clean, clear, no negatives.
I prefer this to previous treatments with Kontak and
Sibilant contact enhancer.

Coincidentally, I thought about adding some copper sleeves to
my system. While I was staring at the Wright's container... how about
polishing my existing copper sleeves? Yes, you will see and hear the
difference. (I use two sleeves at each end of every connection.)

You must use this product!
I picked mine up at a supermarket, and their website has a list
of where you can buy it! $5. A great discovery.

Great results with a single Super Sleeve!

I "stretched " a 3.25" copper sleeve so that it became
oval.  It could now encircle both plugs on a single
wall outlet.

One plug on a dedicated line (SR black outlet) contains the cord
to a SR Powercell 12 and a High Fidelity 0.5 magnetic wave guide.
I used 3 small cork rectangles: one in between the plugs
and the others between the plugs and the body of
the sleeve (top and bottom).   There is an additional sleeve over the SR cord, that is easily fitting inside the Super Sleeve.

I recently treated the wires of the outlet with Total Contact,
and applied it to the face of the outlet, and the outlet cover.

I am hearing a more relaxed, natural presentation
of music, with no fatigue.  Highly recommended.

Ozzy, just try it!

(The $3495 SR cord  is no slouch, material-wise...)

How many times have you been pleasantly
surprised by experimenting?
Conversely, has a "sure thing" ever disappointed?

Great results placing small pieces of foam on top of sleeves
and/or inside of sleeves.  I use something like headphone pads (covers).              
A fit that is too snug (pinching wires inside a sleeve) can dull the sound.

As Ron Hedrick of Marigo Audio has said, "It's all about the details."
Also try pieces of foam on top of components and electronics like FEQ and
Schumann Resonators.  I also use Agora Magic Hexa (tweekgeek) in some
applications... yes, there is magic here.
