If the Denon preference sways you, I think you should follow Thunder's advice, assuming you can find a compliant merchant. j-garcia's advice is very sound considering the price differences involved. I guess it just depends on if the cosmetics or brand preferences will ultimately determine your choice. (The purist and capitalist in me says that these should not be factors, but there is value in liking what you have.) For what it's worth, I think the Yamaha is classy looking, and I like the Denon piece's appearance too, very similar; cosmetically speaking, I would prefer either to an Oppo unit. I don't think the sound would be any better, whichever unit you end up with.
I recently had not one but two equipment failures (universal player and pre-amp), and they are frustrating. Sorry that you are facing this, but at least you are covered and have some options.
OT- j_garcia, my hat's off to you for being the impetus for one of the most hilarious threads I've seen here. I recently read about the guy who purchased an SVS sub based on your recommendation, only to find that it is as big as a refrigerator and probably more massive, and that the sub has bass capabilites far beyond what he expected. That was one of the most entertaining threads on audio gear I've ever read.
