ATI 2505 vs. Outlaw Audio 5000 vs. Rotel RMB-1075
I'm in the market for an amp to expand my 5.1.4 system (with a Denon X4400-H) into a 9.1.4 system. The X-4400H supports up to 9.2 channels by itself. This will be my first entry into external home theater amps.
I have an opportunity locally to pick up either a used ATI 2505 for $700, a new-in-box Outlaw Audio 5000 for $450, or a used Rotel RMB-1075 for $400.
The ATI is an older amp, but it offers 250WPC into 8 ohms or 375WPC into 4 ohms. So it's a good bit more powerful than the Outlaw or Rotel.
The Outlaw offers 120WPC into 8 ohms or 180WPC into 4 ohms
The Rotel offers 120WPC into 8 ohms 200WPC into 4 ohms
As far as the speakers that the amps would be driving; Right now, I have a pair of Wharfedale Opus 2-1's for the fronts, a pair of B&W DM604's for the rears, and a Polk center. I'll most likely let the AVR handle those, along with the subwoofer and Atmos speakers. Either the Wharfedales or B&W's could be swapped out for some Boston Acoustics VR965s or some Tannoy Saturn S10s.
For the FWL, FWR, SL, and SR speakers, they'll need to be wall-mounted, so most likely 2 pairs of Paradigm Mini Monitors. I'll most likely let the amp handle these, however, I'm open to any suggestions regarding which speakers should be paired with the amp vs. the AVR.
I've heard great things about all 3 amps. Which would you recommend?
