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.

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?

I think those are the same ones I bought, made by Rubycon ?
I think once a tweaker always a tweaker, it would'nt matter the price of the system. The tweakin is a hobby within the Audio hobby.

Yea, I'm a born tweaker. Been tweaking since I was building die cut balsa wood model airplanes many crash landings ago. The caps I ordered are radial type, light brown with DON imprinted on them; 10KuF 25V 85" 20x35mm electrolytic. More fun enroute!

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?

Sgr, Yes, instead of hooking the wire from the negative side to the negative terminal on your speakers. Take that wire from the battery and solder it to an RCA on the ground side only. Then just plug it into any open RCA on your unit.

I think the Synergstic and the Audioquest are applying small voltages to the ground. In this tweak we are just using the negative electrons as storage.
Read up on the Audioprism Ground Control, that will explain the concept better than I can.
