Lhf63 - I have been doing some very similar stuff lately.
I recently picked up a nice TV (panasonic plasma) and as such, have been interested in a quality DVD player to go with it. I have a Jolida 100 CD player, which is widely regarded as a "contender" in the ~$kilobuck CD players. It's a really good sounding player.
I have been experimenting with universal players. If I can consolidate all my digital into one player, that would be ideal.
I started with an Onkyo SP1000.

This player easily has the best build quality of any universal cheaper than the $5 or $6k Esoterics. It is build like a tank, and does all the formats.
When I got it, I did plenty of A-B testing compared to my Jolida. The Onkyo definitely sounds better than the Jolida IMO. It really doesn't give anything up, and has a more "open" midrange. The music is a couple steps more transparent - sounds more like music, less like digital.
However - it had a problem with SACD. There was some strange background noise.

So - I returned the player. When I returned it, I found out that I "accidentally" bought a refurb player. Yes, it was my fault, but the vendor had the "refurb" thing pretty discreetly on the page, so...
I then bought the Marantz9600. About the same price as the Onkyo, but with much worse build quality. Flimsy transport. The interfaces for DVD were not as good as the Onkyo, and the remote was much more cheaply made. But of course the important thing, the Jolida sounded better to me on CD than the Marantz. The Marantz had an artificial sounding bloom on some of the upper mid-bass notes which I found distracting, and the midrange had a somewhat "hard" effect.
So - back went the marantz.
I bought the Onkyo again from another vendor (not a refurb this time!) and the issue with SACD is gone, and I love the player!
So - there you go. Good luck. I haven't tried the Denon, but I'm a bit put off by the build quality.
