Matt; Thanks for the advice - you are pefectly correct re the Wattage. I decided on the 800 over the 320 not because of the Watts. I want to see if a larger more powerful SW can match the Ken. Also, in reviews some are faulting the 320 for music (not HT), but no negative reviews at all on the 800. Some weakness is noted concerning music playback, but I played around with the bass management on the YAM & directed it to the BOTH setting (Mains & SW) & since the RT-11's can handle it, it sounds great!
