This is a question for for anyone who's a former Onkyo AVR owner that switched to Denon. I had the 876 for several years, and acquired the 906 and experimented with it for several months. Both when the Audyssey applied, would set the center channel quite low, -6db, while the fronts were plus 1 or so. To get the dialogue to a reasonable volume, any ensuing actions scenes would blast way over the top. I'm a veteran of movie theaters, and they are not supposed to overpower the room like that.
Anyway, I'd have to manually bring the center way up to compensate on both Onkyos. Also, they did a weak job setting the sub, which typically would also be way loud. When I got the 4520, I was shocked how much better the center, sub and surrounds were all set. I've never had to adjust anything, and the action scenes are properly balanced.
What I'm wondering is, is this me or has anyone else experienced this with Onkyo. I'm wondering if Onkyo took a different approach to Audyssey or something.
