OK, I'll add to my original comments on the sound. I've been going over what my original reactions to the 9.8 were when I first swapped out the Denon. I'm not trying to compare the sound from memory, just my reaction at the time.
I recall my original reaction to be that music did, in fact, sound cleaner, more detailed and more dynamic. I was genuinely pleased with what I felt at the time to be a noticable improvement in sound quality. It's been a few months now and in that time I haven't really had much opportunity to sit for any critical listening, so now I think I just consider how it sounds, how it sounds. I didn't have any major issues with how the Denon sounded but I do recall considering the Integra an improvement. Now, the Integra has had some break-in time to adjust my ears to it's sound.
