I added two Monster HTS 2000's for surge protection and their ground breaking feature. I live in an older building with sketchy wiring. I was pleasantly surprised that these inexpensive units also made and improvement in sound (insert the usual adjectives). Each unit has two non current limiting outlets for amps. I had tried power conditioners in their early incarnations and found them to be too "subtractive" in nature, so I had stuck to cheap strip/surge protectors. I'm thinking of adding better quality outlets now.
