Has anyone used/purchased AC voltage line conditioners? I was reading SIRQUACK's thread on hum and static and was wondering if that would help. ( I didn't read the whole thing, honeslty). I've been looking at the APC H15. At $450 it seems like a great investment for expensive equipment. And I run an APC on my computer with monitoring software and I can't believe all the spikes and brown-outs in a 24 hour period. Thanks
