I have had the 990 for 4 years and with the BDP-83SE since it came out a couple of years ago. I have also considered the Emotiva processor but as you say, too many issues and bass management approach that is odd. I listen to a lot of hi-res surround in all formats, especially bluray now, lots of wonderful concerts are available.I was concerned about room EQ as well but made a significant improvement to my room with room treatments on the walls. I wish I had done it sooner. If your situation allows for putting treatments on the walls, I think you will be happy with the results. Basic treatments are simple (Google it) and you can refine further as you see fit. Much can even be done with homemeade treatments. Even if a processor has good room EQ, I feel now that room treatment is a must for the best sound. It is often overlooked or not possible(WAF)for many. You'll be amazed at the improvement controlling room reflections can have, improvements that cannot be had with EQ'ing. Have fun.
