I think that the Sony is overrated in terms of the power output. I found a bench test result saying this:
http://www.soundandvisionmag.com/receivers/2354/test-bench-sony-str-dg910-av-receiver.htmlI have no problems with the power output when playing dvd movies or cd's however I watch a lot of music dvds that many have very low output levels and I need to crank the volume to max and still lacking. I have taken one of these low level music dvds to a friends place and tested it on his system. He has a marantz receiver 80 watts per channel at 0.03%THD and speakers that are 91 db/w/m, where my system is the Sony receiver 100 watts per channel at 1%THD, 8 ohms, (4 ohms ????wpc) M80's with sensitivity of 95 db/w/m. His system is much louder than mine when playing this low level music dvd. I can only think that the Sony output is overrated.
