I would tend to say that you are choosing between three very good products, and I think any one of them would serve your needs very well. I'm one of a number of people happily driving Paradigm speakers with Outlaw amplification, for what that's worth (and of course Def Tech, Rocket, and Axiom are equally well represented). Outlaw's amps have always been well regarded - I don't know how much benefit would be had by upgrading to the Anthem or Sunfire. Some folks around here may have had an opportunity to compare a couple of these, which could be interesting. Just out of curiousity, have you factored in the $100 savings available when buying a 755 and 950 together?
