Ground loop with Miyajima Premium mono


Hi to all,
this is the trouble:a annoying hum from speakers when
the Miyajima mono cartridge play.Aesthetix Rhea phono stage.
This resolved only desconnecting a channel from the cartridge
and selecting mono function from line pre.
Does someone know how this problem can be resolved?
Thank you in advance.

My Miyajima BE Mono should be arriving this week and I look forward to hearing what all the fuss is about. I'll be using mine on a Schick 12" arm.

Lula, I think I can answer your question. Some mono cartridges (such as the Miyajimas) are "true mono" designs that do not have vertical compliance. This type of cartridge will damage a stereo record. Some other mono cartridges DO have vertical compliance and those should be able to play a stereo record without damaging it. From what I have read, Grado monos are in the second group but there are probably others as well.
