Ok, I've been switching back and forth between the Panasonic 310 and the OPPO 83 players, just playing Pandora content. Everytime I switch back to the Panasonic, the sound is more muted, so I know something is going on with the frequency ranges between the 2 systems. All other things being equal. I don't know what it is, but the OPPO plays with better sound. Also in both cases the AVR sets itself to PLII Music. Definetely not just differences in volume either. I turned it up in both cases just to eliminate that possibility.

With Panasonic BR player, I get bass, but nothing exceptional. With the OPPO, I get exceptional bass.
