but I had to buy the Panamax when I was having so many problems here with the power line AC voltage swings here where I live.

I noted highs of 140 at night and 110 during hot days. They have since changed things out somewhere at a substation and its a much better 127/110 now going into the Panamax. But here's the weird thing about the Panamax -

I was hearing a very low level ear to the speaker hum from my electrostats with all amps unplugged, everything off, so I ran a separate AC line out of the wall into them and it was gone. I now plug them into a separate APC and it's ok now. Funny thing is I don't have any other hum problems from anything else with ear right up to the speakers. It does its job very well otherwise.

At the time the Panamax was about 750 bucks. It would be worth a visit to John Risch's website or other places to find alternatives. I clicked on his website just now but got some king of warning
