If you meter the component, there is no real charge on the chassis.But I do believe the "surplus" of electrons as Bud Purvine puts it suppresses some of the EMI and RFI that enters the ground line. Maybe it dithers it ( the noise), but I am not sure of the exact mechanism.
Again a lot of other tweaks are addressing round control issues. I am wondering if we are not all trying to get at the same end result. (Entrec, for example).
All I can say is thanks to Bud for the inspiration.
You'll notice I steal a lot of ideas, but always try to give credit where due.

I built 2 video units (2 47k uf caps with a 0.15 bypass cap connected to a 9v battery) and 2 audio units (1 47k uf caps with a 1.0 uf bypass cap connected to a 9v battery).
I connected the audio units first, using an rca plug on each. One went to the Oppo 105, and the other to the Candela tube linestage. I wasn't sure I liked them at first as the top end seemed a little enhanced. Positive improvements included enhanced tactile sensation with all instruments: horns had more bite, bass more muscular, vocals more present and realistic. The soundstage also seemed a little better. I removed them and the system still sounded clean and quite good, but the improvements went away. Plugged 'em back in and they returned.
I decided to keep them for a while just to hear if the caps underwent any changes. They did and the slightly tilted up high end resolved so that I have all the benefits now without any drawbacks. The soundstage has improved slightly since the first used as well.
The video units I connected first to the cable box and TV, and couldn't really tell much difference. Then I moved them to the AVR video out, and the BluRay player. We spun DePalma's "The Untouchables". I can't say the picture is better because I'm not sure my video memory is accurate, but it was pretty stunning. The thing that both my wife and I noticed is how the speakers disappeared. Sounds flew around the room as if the we were in the scene.
I may remove them to see if the improvements go away.
This is such a cheap and easy tweak. Thanks so much for this Uncle Stu!
I have been using the 6v lantern battery with bypass caps of lower value for the last two years. With the recent post on increasing capacitance, I tried it out and found a huge improvement. My basis for evaluation is the headphone output on my Revox B77 reel deck.
Question for unclestu; With the same capacitance value, can the 9v battery provide the same level of sound quality as the 6V battery? Has anyone compared? I have not tried this so far as I have to buy fresh batteries. The other issue is I have soldered connections to the 6v terminals. Not sure if the 9v batteries can tolerate that.
bravi, the 9V batteries will handle the soldering just fine. If you are concerned about the heat affecting the battery use a small alligator clip as a heat sink.
Or as Tom Lehrer said,
Don't shade your eyes, plagiarise.
Only be sure to call it research.
