I was messing around the other night and decided to put a capacitor between my phonostage bindingpost and the tonearm earthlead....... WOW i have no idea what was going on but the difference was not subtle. Soundstage got bigger Low frequencys improved. I dont know whether i was picking up RF or something else. I can`t advise you on what value cap to use, as i am still experimenting. For the cost you have to give this a go....

BTW you dont need to solder. For testing you can just wrap the ends around the spade of the lead and the bindingpost

Grounded to grounded through cap.....

I definitely feel it cleans up the groundplane...

So that would make them coupled at higher frequencies but not low. Plausible that it would make such a difference depending on the equipment in use. :)

I am sure all tweaks like this are system dependent. It would be intersting to see if anyone hears the same improvement in their System though....

Phonostages are by nature suscetible to noise and humm. One of the defining qualitys of a good phonostage is the absence of noise. Less noise is always better. I did not suffer from any noticeable noise or humm before this experiment. This is why i would be intersted if anyone else notices any difference at all.

What type and value of cap did you use?

It was a film foil cap used for crossovers like 150pf.....
