I had upgraditis for awhile, I've had my 7ii's a little less than a year. I upgraded center to RC64ii about six months before that, a 12" Klipsch sub and repurposed Quintet fronts as new rears. I spent six months reading & chatting about separates vs. AVR for my space. I do almost equal parts audio and video. I've always liked Yamaha hardware, upgraded to A2010 w/pre-outs, so incredibly pleased. now, I listen to music and movies very differently.
music is 2 channels, only 7's, put yammie into what's called "pure direct' mode, turns off processors and the whole front panel display except for a small blue LED. can't really describe how fantastic it sounds, 'unadulterated.' all digital, no physical media. the A2010 has built-in Pandora, Sirius, internet radio, which I've gotten really into. Or, I stream from an i-device.
movies whether streaming or blu-ray from a PS3, full surround, and/or utilizing Yammie's digital sound processing to upconvert audio.
Overall, part of my enjoyment of the 7's comes from easily playing with settings. AVR's built-in speaker calibration software, tight integration with Yamaha's iOS apps (which I still think is by far the best out there right now), and my Logitech Harmony remote = I never have touch either of the yammie's AVR remotes. I can control the sub from the harmony remote.... all without getting off the sofa.
It's all about what sounds good to you - but in my space the A2010 sounds pretty awesome to my ears. I don't feel like i need to add an amp at this point. If I want more bass in a particular movie, i can notch that up remotely. Maybe in the future if i added an amp i'd take out the sub and reclaim that floorspace.... the sub is big footprint, but I think for now, I'm good.
