There are theories that 'hi end audio' hobbists believe the source of the power has to be 'purify or stay clean' before going to all your equipment. That's why these 'power cneter' come into place vary form hundred to thousand of dollars.
Alan of Axiom may like to his opinion this. Whether you can hear the difference depends on one's training (technically and/or psychologically). Frankly speaking, I could not hear the difference when my friend demonstrated his system while I was on vacation in Hong Kong. May be I'm to old and my ear has lost it sensitivity.
I agree with kcarlile. Save your money. If you want your equipment be protected from power surge, just get the normal power surge bar.
The bottom line is, if you have the money and you feel 'more' satisfy with one more gadget, then go for it.
