In Reply to: RE: Copper Union Update Info posted by Dr.Phil on April 09, 2009 at 12:56:25
I do appreciate your experiments Dr. Phil. I added the copper to my digital out shorting pin as you suggested. I already have the copper on the female and male sides of the CD player power cord. I noticed another nice improvement in the location of instruments on the sound stage. This is with a Marantz SA11-SA1 cd player modified by the Upgrade Company. My A/C comes from a PS Audio Premier Power Plant Regenerator. I use the new PS Audio duplex wall outlet. All the unused input, output, balanced connectors are capped with RF shielding covers.
I use 3M easy release blue color masking tape on the connectors to get a snug fit with the copper.
Cost of this newest copper tweek- 75 CENTS!. And if it doesnt't work return it for your money back .
To all those wondering about aluminum tape, get of your ass and do the tweek and report the results good or bad.

David thanks for the kind words. Your right everyone off your butts and give this a try. They are so easy, plus you can easy slip them on and off and see where they work the best for your system.
I mean the digital terminator I did on a whim because I had a copper union in my hand as I was passing by my CD player and I thought just maybe and slip it on. Hit play and the vocals and the bass stood right out as being much more defined and dynamic.
Got up slip it off sat down hit play again and sure enough while very good not as good as with the union on. Slip it back on hit play same repeat imrovement. Done.
Total time used was a couple of minutes.
By the way I did slip some RCA caps on my used RCA outputs on my CD player and sure enough less noise again. I have not tried them on my McIntosh gear though because used inputs are turned off....but then again who knows unless you try.

Well I tried the metal Digital shorting plugs on both the coaxial input and output on my Cary 306 SACD Player and it did indeed make a difference.Suprised that the shorting plugs work both on Input and output on digital.
But, when I added 3/4 copper sleeves over the metal shorting plugs, it dulled the sound, so no go for me.
