Need your thoughts on Denon 3910 vs McCormack UDP1

Avguru: I find it interesting that you mention the Marantz 8400 as one in a group that you prefer--I found the bass to be OK in this unit, but *lacking* in the very bass slam and impact you find lacking in the UDP1. Granted the Marantz is a less expensive player, but surely the UDP1 is better than the Marantz 8400 when it comes to the bass aspects? Are you a salesman who has been able to do good side-by-side comparisons of all these units?

Can anyone comment on the DVD playback of the UDP1?

Wow -I'm so glad to see the action pick up on this and related thread next door!
Avguru - DV50's cost, non-universal, "best w/ balanced" all rule it out.
Ears - I just might see if I can readily find the Onkyo for home audition. But if there aren't major mod options, I am very skeptical it could compete with UDP or Exemplar on redbook, and that is the issue that is most driving my decision.
labtec - thanks for such solid advice. I'm leaning to just getting the UDP, but I'm trying to think carefully about the Exemplar angle BEFORE I listen to the UDP crush the stock 3910, fall in love, and end the investigation.

I will have about 1 more week before I have to decide to keep or return the 3910; so far I've simply concluded that the stock unit's redbook and SACD performance is unacceptable for what I'm aiming for.

What I really need is ANYBODY w/ MODDED DENON IN DENVER AREA?? - Come over and help me settle this!

Bbeezley, I think there are only two Exemplar 3910 done thus far. You are welcome to come to College Station soon to hear mine.

My problem with the UDP-1 is with the video secion. If it had HDMI outputs I would buy in a heartbeat. Component doesnt do it for the new digital TVs. I emailed them and they said that they had no plans to come out with an HDMI player anytime soon. I may get my 3910 modded but there are so many modders and no real comparisons of all these mods to figure out which one is the best.
