Hi Selectric, You are right. While my phono-pre has actually two independant phono-pres the ground connector is common. Both cabel ground wire connected to the pre
ground have some interfirance. Not sure if this is some kind of 'antenna' effect but I hear 'the effect' clearly.
According to some when you disconnect the (phono) cable ground you get symetrical connection with RCA connectors.
I am reluctant to disconnect one of the two cabel grounds
because my rack is against the wall and I nearly got hernia
by connecting both cabels to the common ground on the pre.
I hope someone 'technical' wll explain this issue.
Regards,
