You could ruin your gear. Some UPS only produce a "Square wave" electrical signal. Cheaper to make. Computers don't care. You need a good sine wave otherwise your gear may suffer damage.

APC (American Power Conversion) who is one of the largest makers of computer UPS devices is coming out with a Home Theater and Audio line of UPS gear. They had them at CES. They should be available in the spring.. See the link below..

Computer UPS's aren't designed for high current transients (such as you would get from an amplifier). That's why you don't connect laser printers to a UPS. It might actually damage the UPS.

I just picked up one of the APC units Sugarbrie is talking about, the A15 yesterday. It replaced a Powervar and I'll not go back. I am most impressed with the performance. It has isolated filter banks for "Video" (TV & VCR), "High Current" (Amps & Subs), "Digital" (all the rest), 3 sets of coax, phone jacks (1 in, 2 out), IEC (with what appears to be a 12ga 8ft power cord). After setting it upand powering up, I thought my Sony Wega 35in CRT was almost an HD, the audio sounded more coherent and the blue lit front of the A15 is just plain cool. Oh, I forgot to mention that it provides adjustable Voltage Regulation. The surge protection seems to be second to none and is fully guaranteed. I'm quite happy with it.
