So it sounds like the M80's maybe are the choice.... so far. With that said, what AVR makes sense? Denon 3808 or the Yammy Yamaha RX-V3800 ???
I researched the hell out of Panasonic 84's and Marantz 8001's a while back. I bought the Panasonic 82TX and Marantz 8001's. I prefer the 8001's for the most part. The HDMI switching works fine, sound is very nice and it does what I need it to do. I too toyed with 80 vs 60 and finally opted to go with the M80s. I didn't want to "regret" not going for it when I had the chance. For reference, I have the M80, 150's, 2XQS8's and EP500. I love them!!
