I have this on order.

I have a Furman SPR-20i, purchased from Ivan. It can handle up to 20 amps and has 12 outlets. Before this I had a Tripplite LCR2400, which is also a voltage regulator, but it didn't have protection for cable/satellite as the Furman does. Your unit has UPS, which the Furman doesn't.

I don't know your setup, but if you have cable TV connected to your system that could be the source of the hum. Or a ground loop, perhaps; those can be tricky to track down.
