So I'm very sure at this point I'll go for a Yamaha receiver. Now deciding between the A1070 which I can get for $600 or the A2070 which I can get for $800. That's 110W vs 140W in 2ch, which will be my primary use. Are there any other important benefits I'd get by going with the A2070 over the A1070, besides more power/headroom? I'll be driving a pair of Revel F36, which dips down to 4ohm at certain frequencies so I think the additional headroom wouldn't hurt.
My main reason for picking Yamaha over Denon is the supposedly higher reliability and the fact that the Yamaha Android apps, which I'll be using a lot to stream FLACs off of my NAS server at home, work very well and bug free, whereas the Denon apps are horrible. Maybe Audyssey XT32 is slightly better than YPAO, but I'll get a UMIK-1 + REW and will do some manual EQ once I get around to it. And once it's set I won't have to touch it again for a long time. Whereas I'll be using those apps daily, and that experience will be more important
