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.

You resolved it by using one channel as you said and them using the mono switch. Both channels Contain the same
Mono track. Pluging them both in doubles the ground and causes the ground loop hum.

obviously Robin is the expert here. i had the same problem with my Miyajima Premium Mono, called Robin, and he gave me the same answer.

i've been listening that way for 6+ months and works great.

enjoy!

stunningly good sounding cartridge.

Robin, Do you mean to say that this is the usual recommended mode of operation for the Premium mono (one channel hooked up and preamp set to "mono")? Does this mean that one would have to tolerate hum (or sound coming out of only one spkr) if one's preamp does not have a mono switch?

Lew,

you can do the same thing with interconnects that a mono switch will do. so it's not a limitation not having a mono switch.

you simply have to rid yourself of the ground loop.
