I'm in the process of upgrading my DVD player and amp. Have just gone for the Panasonic DMPBD50, and want to make sure i pair this with a suitable AVR. Looking at Onkyo 506, but can this handle HD audio via the HDMI as it hasnt got build in decoders? Or should i be looking at the Onkyo 606 which has? Any help on setup or selecting the right amp would be appreciated.
