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.

Glad you guys tried the tweak and have had a positive improvement.
I wonder why more Audiogonners have not posted?
Anyway, do try using the 10K caps it will improve still further.

Ozzy - I read your post with interest. Trying cheap tweaks is definitely a fun part of this hobby. I'd like to try your cap/battery tweak on my speakers but want to be sure I understand how to implement it. Do I have this right?
1) Install the cap across the battery terminals (- to -; + to +).
2) From the negative battery terminal, run a single wire to the negative terminal of the speaker.
3) This set up is duplicated at the other speaker.

If I have it straight, seems like something even I can do.

Thanks in advance for your reply.

Ghosthouse, Yes you have it right!
You can also use it on your CD Player, Preamp etc. just by connecting the wire to the ground side only on a RCA.
Give it a try, and post your results.

Thanks, Ozzy. It'll take a little time to collect the parts but I'll report what I hear.

Just ordered 10 ea 10K caps from eBay for $15.09 total. Seller is local so should receive them by midweek. I wonder if these will bring me to the point of diminishing returns on my system? Maybe an alarm system or motorcycle battery next!
Just thinking, if I were to come into big bucks and could buy any so called hi-end system I wanted would I still have as much fun as I'm having tweaking my present system?
