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.

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.

Ozzy,
How long does the the 6v lantern battery last ?

Since it is used as the ground and there is no actual current running through it, the battery should last as long as the battery has shelve life.

Well that's good to know, thank you.
Ozzy, I experimented with different quality electrolytic capacitors.
I found on my application the Elna RFS Silmic II 1000uF 50VDC to be
incredible, the dynamics are explosive, and the noise floor to be the quietest ever. I'm thinking of adding another set on the amplifier side soon.
More to discover
