I also spoke to my colleague, Amie, at Axiom. They had a huge storm and power surges/outages a few weeks ago. She also has an APC/UPS unit (about $300, she said) for all her computer stuff and none of that was damaged, nor were any AV components that were plugged into(inexpensive) power bars. However, the gear that was not plugged into power bars, including two EP600 subwoofers, had the amplifiers totally fried. So was a prototype Axiom power amplifier.
