Down the road I may add a Monster Power Center to my setup but its the cost that keeping us apart. WHile in a Local Best Buy I came across Battery Backup units that contain AVR(Automatic Voltage Regulators). Would this work along the same line as the Monster? Here is a link to one of the units.

Most UPS units do not condition the power, and even actually degrade/deform the pass-through AC power. They assume you have digital devices attached so messing with the smooth AC waveform does not affect the computers.

Your HT gear has a very power-dependent analog piece.

Keep in mind that a $10 power strip with "surge-protection" could also be described as having a "Automatic Voltage Regulator". It's a $0.95 device that connects between the two AC wires and clamps/shorts any voltage that goes over about 120 volts.

If you do buy a power conditioner, get one from a local store with a good return policy. Then test the unit in your home at the time you would normally use your system.

Hope this helps.

Most surge supressors actually don't act on the signal until more like 170V, so not a good voltage regulator. Meant more for lightening strike type spikes.

I read/heard a long time ago, that most battery backups don't supply the AC in a true sinusoidal form like we get out of the wall. Most of the (cheap ones, anyway) do square waves. Not what your equipment is designed for, although I don't know what the effects would be. Plus, you'd have to make sure that the battery backup can handle your system: at least 15A, 1800W capable. (Has to be able to handle transients too.)

Something like the Monster 2500/5000 (2600/5100), or Adcom 615 is a nice compromise solution IMO.
