I use the 3805 to power surrounds and back in 6.1. I added monoblocks across the fronts for my 80s and 150. I listen at reasonable levels. The Denon has plenty of power but I like the sound of my 80s with the monoblocks.

I had 60s first and upgraded. I didn't have to. I could afford to. I didn't have to get a 500, I just wanted it. (The 600 didn't pass WAF)

I have more than I need but I am a happy camper!
