SGMD1, the reason to get a player like the 5910 is to use the player's audio DACs, not bypass them with digital outs. Also, the 5910 outperforms the Oppos for SD DVD PQ as well. I agree that there are diminishing returns as the price goes up to that amount, but for those who can afford a player like the 5910, it is second to none (and is a far better player than any Oppo for PQ, audio, and build quality).
Why even ask such a question? It may not be for you (or for me). But why disparage others who have gone that route? Denon has sold plenty of them, so clearly they do not think it overpriced.
