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.

Well I now have a bi-wire speaker cables and I have just connected up 2 sets of 6V Lantern Batteries with 10K Caps at the speaker ends.
Wow! What a satisfied sound. The best I can describe it is, the music sounds relaxed and natural.

Now, I know I have raved about this tweak for some time. And there appears to be 2160 views on this topic thread. I hope I have encouraged some of you Audiogon tweakers to give it a try.
Hi Ozzy

To recap. You've got 2 sets of 6V Lantern Batteries with 10K Caps at the negative speaker ends of your bi-wireable speakers. You also have 6V Lantern Batteries with 10K Caps on your amp end. Then you have the 9V batteries and 10K caps on your ICs from source to preamp and preamp to amp?

I'm just trying to get a sense of how much is needed to get the results you have. So far I just have 6V Lantern Batteries with 1000uf 50V caps on my amp side. On the speaker end I have wire and ferrite choke cores. My results have been good to my ears. I may try more of the 6 Volt batteries with higher value caps later.
Jedinite24, That's correct.
The 9 voltage batteries are more convenient to place and I think they perform better than the 6 Volt Lanterns on source equipment. With the 9 Volt battery I am using 10K 16 Volt Caps.
At the speakers and Amp the 6 Volt Lanterns sound best but they also need Caps designed for higher voltage like the 10K 60 volt you have.
Well, I have changed my mind on using the cap/battery on RCA source components, at least in my system. But do try them there yourself
Too many caps/batteries upstream on the source components and although they still widen the soundstage I think it thins out the bass.

So, just using the 2 sets of 10K 50 volt caps with 6V Lantern batteries on my bi-wire speaker cable ends is all that is needed.

But, another discovery is on my video. Using an RCA with 10K Cap and 9V battery seems to add more detail to my big screen LCD picture quality.

I still dont understand it, but well worth the experimentation.
