Denon AVR-987 Sound Question

[meckel]

I plan on doing some rewiring today , but I have a question.

My current set-up for Blu-Ray is. Sony BDPS-300 HDMI to the TV and the optical running to the AVR-987. This is how the DVD player I replaced was set up. So, I plan on running the HDMI into the AVR-987 and I was wondering can anyone tell me what the best sound setting I will get?
The receiver is a little over a year old and my wife may actually kill me if I replace it

Thanks for the help.
