Best DVD for my System


I am looking for a DVD player to go with my system. I have the following equipment:

Krell HTS processor
Krell showcase 5
Revel C30
Revel M20 x4
Revel B15 x2
Audioquest diamond interconnects
Pioneer elite 61” rear projection

I was looking at the Sony DVP-S9000ES. I thought maybe I would have the transport mod by www.empiricalaudio.com . I am looking for a great DVD transport. What would you buy?

You say it is a no-brainer, esp for the $$. What does this mean?
I want to know what the sound is like on a high end system. Do you really get authoritative low bass? I tried a low cost pioneer and the bass was not there. The top end was not as smooth either as say a Denon 9000. How would it compare to a Denon 3910 in terms of sound quality? We need some kind of rating system. If the sound is as good as the Denon then I would buy one. Has anybody compared the sound quality from this unit?
Coxhaus,
For video only, it's great.
As far as audio quality, I would email Cinematic_systems and ask for advise.
