Sometimes I hear a deep buzzing sound with my melos on both channels, all three inputs, even when nothing is connected. Sometimes it is there, other times it isn't. Is it a power problem?

Jon:

Have you tried a power filter stuff? Or, can you remember whe power usage condition in your house when you notice buzz like that? eg. washing maching was running etc.

I am hoping that it is a power problem because that would be easy to remedy

It happens when I have a bunch of stuff on: washer&dryer, couple computers, heater, etc.
