I'm still running an Onkyo 797 and its power is ok but there are times when i know it is running out of headroom. I plan on bringing down my Anthem MCA30 amp from the upstairs system (which cannot fully power our Tannoys sadly) and have it run the M60s and VP150. Since i run the M60s full range, it should help smooth out the loud and low bass passages when the system is up higher when i'm out in the pool room or the wine cellar.
Other than its limitations as a 6.1 system and a fixed crossover frequency, that Onkyo has done well and run 4 ohm speakers in the past without any issues.
