It's not that they didn't work ... it's just that Denon 4311 gave me better sound for movies, BUT regular TV programming wasn't as good. Sound was as if a bit dimmed down. Movies however, were very nice. And still ..... for $1,600 I expected a huge difference that I did not hear.
Onkyo 818 was similar to Denon but not as good.
Keep in mind ... i was too lazy to dig into the manual and read everything. It was more poking in and out, pushing buttons and trying to hear the difference. I am sure that if a professional who knows Denon 4311 in and out stopped by, he'd do a much better job.
