Just waiting for my PS3 to arrive (for Blu-Ray playing!) and currently have a Denon 3805 receiver. This doesn't have HDMI input and, so, I guess I am limited to the Optical connection. From my limited understanding of the audio options for Blu-Ray, this will not be the best audio option and I am thinking swapping for an Onkyo 605 so that I can take advantage of the new audio formats. If I do this, would I connect the PS3 to receiver, via HDMI, and then have to run another HDMI cable from the receiver to the screen? Would I be able to hear the sound through the TV speakers, if I wanted to? Thanks!
