The next best Tweak ???


There have been several postings at AA about a new tweak from the mind of a gent named unclestu that I would like to share with Audiogon members.

I really don’t know why it works or how it works.
This tweak will cost you about $10 bucks but hold on to your hats...

unclestu discovered that the Ground Control (that was designed by Bud Purvine and sold by AudioPrism)design could be improved on.

You will need to make two sets for your speakers.

What unclestu came up with is to take a 6V Lantern Battery, add a 1000uf Electrolytic capacitor across the top springs (+ to + and - to -) connect a wire to the negative side of the battery and then attach the other wire end to the negative post on your speaker.

I have also made a couple that I plug in to my Preamp and Amp. Those were made with RCA’s ground on the wire end and I used 9V batteries utilizing 9V battery clips.

I've got to say, big improvement across the board, Soundstage, bass, mids, treble. But the most dramatic change is in the dynamics.

Hi,
I get how to hook up the speaker and amp part of the tweak, but I'm confused on how the systems for the RCA, Balanced, and digital connectios are made. Do you just construct the same apparatus using the appropriate connector and plug this into an unused input on your preamp or DAC or are you building this circuit into an existing interconnect? Also is this tweak accomplishing the same type of system Synergistic Reseaerch and Audioquest use on their cables except this is allowing it to be done with cables of your choice?
Thanks Ozzy for your help. I have implemented this on my system. I have the 6 volt system on my Legacy Helix speakers and had to make a special rig since the speaker is quad amped. It took a while to figure how to do all thee speaker terminals for each speaker but I got the job done. I also made the rig with the nine volt batteries one for my Perfect Wave DAC and one for Ref 3. The tweaks make a subtle but worthwhile improvement. I believe it lowers the noise floor which lets little subtle details escape from the background. Voices seem silkier and more natural.
Soundstage seems to be wider and deeper. It is funny that one can hear the system improve as the caps charge up. I'll bet there is a break in period as well.
For those who have made the devices for the speaker terminals on your amps, did you use 6 volt or 9 volt? Does one find the same improvements? I wonder is this tweak could be implemented on my server and power conditioners as well? Any ideas?
For the small amount of change and investment in time this tweak pays off handsomely.
A friend with a very high Rez system did the tweak for his speakers with great results similar to what we've found, but it did not work well with his Gryphon preamp or Theta Gen 5 DAC. The tweak shut down the soundstage and the system sounded constricted. So this tweak may not be for everyone.
Again thanks for all the ideas and descriptions of this tweaks virtues.

I'm getting some strange pops through my system when I turn the amps on so I had to disconnect for now. I'll show an electrical friend what I've done and see what I might have done wrong. It maybe because I have no crossover in the speakers. Last night I hooked it up after I turned the amp on. Any ideas? It doesn't seem to happen when I just use the ones hooked to the pre and DAC.
