Here is a thing I have a denon avr-791 receiver which is a 90 watts per channel. I 'm thinking to replace it with a Marantz sr8002 which it sale on ebay from time to time. The sr 8002 is a 125 watts per channel thx certified. It will really make any improvements in sound those extra watts? I'm also looking to the denon AVRS 910 which has the same amount of power of my current denon but with the all new technology. I don't really care about dolby atmos or dtsx, ceiling speaker is way to ugly in my opinion. The think is a extra 35 watts makes the different in sound. Sometimes I crank up the volume to hear the hulk screaming in anger in avenger, that why I consider swapping receiver. Thanks for all your comments
