RE: It Works!-Final Thoughts




After playing around with these tweaks for a good few weeks now I would like to share my thoughts. Therefore, you know my system.

AC Outlet of choice for McIntosh amp Telsa Plex, front end gear McIntosh C200 and Marantz SA-7S1 with Porter Ports.

Copper unions: One on the amp and preamp IEC and one on the male plug AND the IEC of the CD player. Adding another on the male plug dropped the noise floor even lower and opened up the sound even more with outstanding body and detail. Adding them to the male ends of the amp and preamp male plugs dulled the sound out, perhaps to much of a good thing.

BNC and coax digital out terminated (a must on any cd or transport) and lastly the ground wire to the chassis and connected to the ground pin of ac plug and plug it in without the other pins of course on the ac plug pulled from my system.

This was a tuff call, but the ground wire it seemed to lean thing out, hurt the body of the music and almost create ultra detail with a loss of warmth.

I sat, plug, and unplugged the cable several times and every time the system snap together better without it. In fact playing a few cd's that I had not played in awhile snapped me to attention because they were missing something, so I pulled everything off and started over and the last thing I tried pulling was the ground wire.

In every case each of the above improved the sonics of an all ready good sounding system even without the above, with them a huge step up in musical enjoyment with no negatives.

Another shocking thing was adding the two copper unions on the amp and pre IEC end and then taking them off and listening to the same track again, a 50% loss of the improvements gained.

Also the same when I added the extra union on the male plug of the cd player.

Key point here is the system did not sound like crap it sounded good without zip, but with all the above a totally improved system top to bottom.

It been fun playing around with these cheap tweaks and what I learned is to let it go and try different things and take your time. You have to have a good ear also to crasp the change.

I think Al stated that adding the ground wire could create noise in MY case I think he is correct.

I think for the money spent and some time given this is just the best bang for the buck I have experienced in audio in 30 years.

Have some fun and play.
