Hi all, here is a bit of an oddity that i am struggling with.
I have a MF M3si connected to a part of Monitor Audio Silver 8 towers. The amp is feb by a mac mini via USB.
I hear a constant 60Hz hum from the speakers at all times (independent from volume setting). No matter if anything is connected to the AMP or not, no matter which outlet the AMP is plugged into, and no matter if the AMP is plugged in directly or via a ground lift. I have also tried two different high quality power conditioners, with no effect. And 4 different power cables, again pretty hight quality, with again no effect.
I know that it isn't the AMP because at my dealer's there is no hum.
Its also not cross-talk because the speaker cables do not come even close to any other cables.
And, I also get the same hum from another integrated AMP I tried, and older Arcam unit, which makes me think that its not the MF.
At this point I am at a complete loss as to what it may be.
Any and all ideas are welcome. Please.
Cheers,
