I'll probably get hammered for posting this on this forum, but unless you have very dirty or intermittent AC, I'd recommend placing your priorities on surge protection for your components. Adequate surge protection is available for a lot less money. In the P5 and P10 demonstrations that I witnessed, I could not discern any sizeable improvements in sound quality from the McIntosh systems involved. I'm not saying that these items won't provide any electrical benefits to your components, but two of these items would be a hefty investment for what I consider to be minimal overall sound improvement. Of course, the best thing to do is to try them out in your system to see for yourself. PS Audio has an excellent 30 day satisfaction guarantee.
