In Reply to: RE: The Physics of The Battery Ground Tweak posted by Maxamillion on December 12, 2015 at 15:44:53
My thoughts on the matter are that the battery and circuit are an antenna, picking up on the ever increasing array of electromagnetic noise that's in the air.The sound is modulating on top of the noise, making a change that can be perceived. The effect of the charge from the battery would be much smaller and swamped by the noise.
A practical test would be to use a dead battery and see what happens.

If you can reliably hear a difference, then why bother theorizing? Conduct experiments to see what matters and what doesn't. The suggestion of a dead battery is a good start. On the other hand, if you can't conduct these experiments because you can't reliably hear a difference then why bother trying to explain the tweak?

That's a possibility, and one I thought of way back when I first read about this. Actually, that's why it took me this long to try it. I can't however reconcile RF pickup with the bass impact and dynamics I heard once I tried it; to my experience RF pickup results in harshness in the high frequencies, which is quite the opposite of what I've heard with a battery and big electrolytic - it actually sounds a bit warmer and more punchy with the BGT in my system.Interestingly, the effect of a bypass cap across the big electrolytic is readily heard as a tilt to the upper frequencies which I find unpleasant. I've tried a 4.7uF Solen and a 470uF Oscon and liked neither.
Thanks for your input!
