Greg, you might want to ask Emotiva how much current that amp will draw under normal and "loud" conditions (pretty subjective, I know, but I'm guessing you all could talk through it).
I'll preface this next remark by acknowledging that my Belkin PureAV is not showing peak power draw and is showing more of an average (at least, it sure seems that way to me). That said, while playing a 5.1 concert DVD on my system at what I would consider a loud volume...with my RPA-1 powering the fronts, Pioneer powering the other three speakers, PC13-Ultra going, CRT TV on, and DVD playing...my Belkin shows a current draw of between 2 and 2.5 amps. That's why I'd guess that you don't need it, but as avaserfi said, it sure won't hurt.
