Almost ALL AVR companies lie about their power numbers. Yamaha on their lower models does this all the time. For most people, it means nothing. They won't have a problem in their room with their speakers and their preferred listening level.
Sound and Vision put the 661 on the
Test Bench and at 1Khz (not 20-20,000hz which is a better real world test) it put out 56w/channel pushing 5 channels (at clipping). At 20-20,000hz the number would be much lower, in the 30's per channel. If you are throwing something that is putting put peaks to all channels the Yamaha will shut down. If you bought a 200w/channel amp you would gain about 8db of headroom.
When you look at AVRs power numbers look for number of channels driven and 20-20,000hz (not 1khz). Usually it is 2 channels driven.
Onkyo does this and says it well. Yamaha for the 665 just says 90x7 at 1 khz.
I thought the 661 had pre-outs but I guess it doesn't. What would you want to spend? To get the power you would want I would do a 663 or 665 (which have pre-outs) and get an Emotiva
XPA-3 or
XPA-5
