Hi-end DVD/CD Machine vs. Hi-end CD Player/Transpo


Has anyone done any audio comparisons between hi-end DVD/CD players and hi-end CD players? Assuming that there is a compromise in the audio, just how much is it?
examples...
DVD/CD: Theta DaViD II, Proceed PMDT, Meridian 596...etc
CD: Cary 303/306, NuVista 3D, Electrocompanient, Levinson No39...etc

My listening room is set up for home theater, but I mostly listen to 2 ch stereo. Whenever I make a trade-off, it's in favor of 2-ch stereo. So I'm debating keeping Pioneer Elite as the DVD source and getting a good CD player or going the DVD/CD route. If I go DVD/CD, it will need to be upgradable to DVD-A/SACD some day. If I go with a good CD player now, later an upgrade to a DVD player with DVD-A and SACD (and presumably very good CD) with make purchasing a CD player now obsolete or at least redundant.

What do you think?

Looking out into the future there may be a 2ch pre-amp...

I run a Theta DaViD with a Theta Casa-Nova into two Classe amps now. This has satisfied my craving to upgrade for quite some time. If I had the money however, I'd use the DaViD II into a Casa-Blanca II with extreme dacs then top it off with a Dreadnaught and a pair of Citadels.
I use a Faroudja DVD player. The sound portion of it was designed and built by EAD. The sound quality is incredible.

For CD I use a Classe Dac 1 and a Classe CDT transport with a Genesis digital lens.

On its own the Classe is noticeble better but I run my dvd player through the same dac and digital lens. Side by side the Classe is still a bit better but not much.
"... there is a compromise in the audio, just how much is it? ..."

That is a misconception, 100%.
The compromise are the players that do not do both, but they are disappearing fast.

Also, your list of players excluded a unit that outperforms all of the products you mention for 2 chnl sound, and even more so for the video capability; Muse Thalia Gen 2 (or the Gen 1 for that matter).

FYI -

If DTS DVDs are important to you, avoid the Faroudja (Toshiba based 3006) DVD player. It does not send the DTS signal, but a great transport.
