get a isolated transformer
Ash
I isolated all my equipment by adding an isolated 15 kVA transfomer. That'll give you 5 to 6 20A circuits. it requires a 100amp breaker off the mains, feeding a primary coil (in us=120/240V). The 2nd transformer has its own isolated ground. Then the 5 20A secondarys at 120V.
Once plugged in to the 2nd transformer, the audio equipment is COMPLETELY isolated from every mother loving fan ,computer, clock, or electrical device.
Results>>>>bingo all hums eliminated, and I have 15 amps, so it works. It also helps to use balanced audio connections only. But the you knew that.:D
I worked on these problems for two years, this solved all issues associated with hum and electrical interference, and is sure fire >> at a cost of 400US.;)
Just as Bo suggests......

This is EXACTLY what I suggested, and how I fixed all ground loop issues in a multi-amp system.:D
