Mostly i play prototypes without case. I connect the tonearm ground wire to a star earth usually and from there i do a wire to the turntable chassis so in my system everything is connected to main earth. I may have an unusual quiet earth though because my listening room is on the ground very near a long copper pole that is buried into the ground.
My main power for my system has a separate wire and silver fuses and special hall effect circuit breakers that are not in the signal chain.

But do you reference your riaa amp circuit to that mains earth ? Or do you leave it floating without any connection to the tonearm gnd wire ?

Today i visited Mundorf. They gave me some new toys, silver-gold wire and the new cute EVO caps. We had a discussion about teflon caps and so far they are not happy with the tightness of the winding. Also copper foil sounded worse then metallized aluminum. They think because mechanical stability is more important. Pick your poison.
Thanks Raimund and Mirco.

Yes. It works in my system but it is important where the star ground is.
With stereo it is simple, i use batteries mostly anyway so i do the star between the batteries. Double mono is more complex. Honest i play around until the hum is gone.
Even a small hum can totally destroy the bass performance. Dead quiet is mandatory.
