I'm still debating on whether to get the 505 or 605. If anyone has a picture of their setup for the 505 via HDMI, then the opt or coaxil out (for audio I guess).. Even better if someone has a pic of their 605 setup as well.. I'm still not grasping how the connecting will differ for these two units when connecting a HD or Blu ray player via HDMI... I appreciate any feedback...
