Considering Emotiva XPA-5 or Outlaw Model 7125
I'm considering two different amps to match with my Onkyo NR-807. I will not be able to upgrade my speakers in the near future, but I am currently interested in powering the Polk RTi-A7 and the RTi-A6 for the front soundstage. Both of the amps have advantages that I'm interested in, such Watt/Channel or number of channels.
Would the Outlaw Model 7125 (at 125 watts per channel) be more than enough to power the A7's? What should I be aware of when considering these two amps?
Since the question comes up fairly often, this will be primarily for movies, although music is played on my system fairly often as well.
