I have a non-HDMI HK reciever with 7.1 channel analog audio which I use with my Panny DMP-BD85K. I specifically bough this Blu Ray player cause it had 7.1 channel audio output and I did not want to upgrade my receiver than.

The sound is very saitisfying. (I haven't heard how an HDMI would sound like, but I do really like sound on my current set-up). I have taken great effort to install wall plates for 7.1 channel audio and bought individual audio cable to send sound to my speakers (I only use 5.1 channel audio though). Also I spent 2k on Epson projector one year ago and I have no intention of upgrading that for 3D any time soon.

Now I am thinking of upgrading to HDMI receiver but I wonder even if it is worth it? Would I get a better sound than 7.1 analog?

Any input(ha ha) will be appreciated.
