I know it may not mean much, but even though I've had some shaky experiences with my Denon's, I don't think I would go with any other company. The first Denon I got (an older model...I think it was a 1705, I'll have to check when I get home...) wouldn't turn on. It was replaced the same day by a guy from the store where I bought it. He even helped me set it up, for free even. Was really nice. Never had an issue with that receiver, and it still works, though it's not in use at the moment.
My 3311 that I'm running now used to freeze sometimes, but a power pull would fix that. OVer the years it seems to have sorted itself out, and is a rock-solid unit. I love my Denons.
