Need help with Blu Ray upgrade


I audtioned a Pioneer Elite bdp95fd in my system and was dispointed with the audio portion.
I currently have:
1 Denon DVD9000
1 Krell HTS
1 Krell Showcase 5 amp
4 Revel M20
1 Revel
2 Revel B15

The BluRay picture was much better, but sound was very lacking compared to the Denon DVD9000. I just want to improve the picture quality but I want the same level of sound as the Denon DVD 9000. I am connecting the TV with HDMI and the sound using coax into the Krell processor.
Would the Marantz BD 8002 meet my requirements?
I am also trying to hold costs down so I can buy new stereo speakers for my tube gear. I know my system is starting to get old but I am happy with it.

coxhaus
I was thinking the SE verison of the Oppo 83 is for analog out. I am using the coax out which is a digital bit stream out. Is the SE version really going to help? I guess the other question is should I be thinking of using 6 analog outs instead of 1 coax digital connection?
