But the Oppo isn't a universal player, Spiffy. It plays DVD-A, but not SACD. And I think the Denon 1910 plays neither hi-res formats.
The Denon 2910 is a universal player, but the cheapest I saw it online was $569 US. I considered recommending you the player I bought -- the Pioneer DV-588A -- but the fact that it doesn't pass blacker than black information drives me nuts. Other than that, it's a pretty phenomenal player, which you can grab for $110 US.
I was looking for a universal player a few months ago, and in my neck of the woods, the only universal players I found under $300 US included the 588A, the Pioneer DV-578A, and the Samsung HD841. I picked the 588A for the lightning fast layer change.
There's also the Pioneer Elite DV-45A, which I saw for $305 US. People seem to like it, even though the benchmark guys gave it a low score. Also, there's the Samsung HD950, which still isn't on the benchmark, but can be had for $180 US.
Good luck with your decision!
