The Pioner will certainly give more up to date connectivity with HDMI option, will also upscale video and give you HD sound via Blu Ray. The Denon was obviously a high spec, very competent receiver in it's day so as far as playing music through both is concerned I would advise a demo...
I'm mainly interested in the movie performance although a reasonable m performance would obviously be a bonus. I have another system that I intend to use as the main music player. Just wondered i I would get some gains in audio performance,
