3 channel ht .... pro logic vs dd

Hello members,

In a 3 channel only ht configuration (l/c/r/sub), are there substantial diferences between using a Dolby Pro Logic processor vs a current DD processor. I'm only concerned with a setup that consists of the front 3 channels and a subwoofer. I currently own a once top flight DPL processor (Kinergetics KPS-2) and would like to keep it unless of course I'll get considerably more from a current DD processor from its front 3 channels only. If center channel only serves to localize dialogue from the center of the screen, then I may stay with a 2 channel setup and find the center image or sweet spot between the two speakers. I'm strictly a 2 channel enthusiast and just playing around a bit with video.

Thank you in advance,

Al

My informal playing around found that Dolby Digital sounds cleaner and has more resolution than the older Dolby Pro Logic. The rear speakers don't have much to do with it.

I think that Dolby Digital has the advantage because it uses 5.1 discrete channels of info rather than trying to create separate channels from a lower quality stereo pair. A Dolby Digital processor should be able to mix the digital signal down to two or three channels, plus sub.
