I started out looking for a simple used Parasound Scamp($100)to use to auto on my subwoofer amp and EQ. Now, after reading innumerable marketing crap about filtering, regenerating and conditioning power, I am up to a budget of no more than $700. Here is what I NEED: - 12v or signal sensing, sequential switching for my subwoofer amp, zone 2 amp, plus an EQ - This must not limit current draw and support at least 15amps since my amp is a Crown K2 and draws alot of current. Here is what I'd LIKE additionally: - some type of power conditioning or filtering or something which may make my system sound better. I am considering the following units: 1. Panamax Max 5500 ($570) 2. Monster HTS 5100 ($525) 3. Adcom ACE-615 ($329) Which would you get and why... or would you recommend some other unit that meets my needs, and of course, costs less than $700? Thanks for your help!
