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.

I received my 10K 25V caps yesterday. Removed the 1K caps from the speaker ends and installed these and let them set over night. I just finished listening to "Memories of a Geisha" and I love it even more now. The sound stage is deeper, instruments clearer and the bass is mo solid. I'm now going to replace the 1K caps at the AVR and CDP.

Last week I install a 9V battery to the plasma and was rewarded with a positive visual enhancement. All this for just a few dollars.

Sgro, What type of cap are you using ?
Just a thought.. Perhaps you are using Caps that are too low for your Amp/speaker.
I am using 10K 50 Volt.

Anyone have a idea as to how long it takes for a 10k cap to charge when connected to a 6v lantern battery?

Pixelphoto, Mine seemed to sound pretty good right away.
However it seems to get beeter in the bass after a few hours.

Ozzy, the same here (hear). I recently bought a NAD C 326BEE intergrated amp.; burned it in for 4 days nonstop. Played some Diana Krall and noticed that most of the sibilance I always heard was almost gone. I attached a 6v battery with 10k cap to the amp and that eliminated the remaining sibilance. All gone, banished. There is much more to be said about this tweak but I'll end with, I'm really happy I found out about this tweak.
