If you're satisified with the audio from the AVR, you may simply want to consider upgrading to a dual HDMI 3D Blu Ray player instead so you can pass the 3D video to the TV directly and the HD audio to the AVR separately.
I love this receiver. Could you recommended me a 3d bluray player. That has 2 hdmi. Now for the video one hdmi will go out from the player to the tv. And the other hdmi for the player go to the receiver. Is that right.
