Well, two things about that Gene................................didn't the review on the 2910 say that it's internal parts & build quality were exceptional?
And if the Marantz is indeed "in a different class" & is 3X more expensive, then shouldn't it be superior to the cheaper Denon unit?
Unless I'm reading this incorrectly, they both scored the same as far as performance & value (4.5 & 4.0 stars respectively). Unless these are being compared strictly to others in the same class or price range I don't see how you would choose the Marantz over the Denon.
I'm not trying to be critical of the reviews or the reviewers, it's just that I happen to be in the market for a universal player & am trying to gather all the info I can. I mean, put yourself in my place for a moment

.............I don't have any experience at all with universal players so I'm leaning on the reviews here to try to make a good decision on a unit to buy. If I can get good performance for 1/3 the price ($580 @ a local in this case) of another "good" performer why wouldn't I?
