Well i have owned HarmanKardon, Denon & now Yamaha recievers. They were all excellent but i found that the Yamaha really opened up the sound in my speakers. It really comes down to set list but also depends on what speakers you will be running. I truly believe that each brand does have its own sound to a small degree. My Denon had a bit of a dark/laidback sound while i found the Yamaha to be more open/crisp. So take that for whatever it means.
As far as room correction, i dont see much if any difference in real world listening environments. Ive experienced Audessey, YPAO, MCACC & Trinnov. They ALL do a great job at getting you started in the right direction but they ALL need further adjustme t to be correct. But once done they sound great. Just dont make a decision based on the room correction alone!
One thing i love about the Aventage line is the individual channel parametric EQ including each subwoofer which is great to fine tune. My center channel was a tad bloated so i made a small tweak in the PEQ & problem fixed!
Denons are a great brand & make a great product but my recomendation it by far the flagship Aventage RX-A3000. I have the RX-A2000 & absolutely LOVE it!!!
Hope this helps, if not then just ignore it....what do i know afterall.
