I have the Panny also with the 92txh. When switching audio formats, do you really hear a difference in the sound quality? I really can with some and then others are about the same. Inside the 92 there is a feature called dialnorm that automatically raises and lowers the volume of dd tracks to compensate for differences in volume. Really sucks when trying to see the difference in formats. I've tried everything from 300 to Casino Royale and not really a big difference. Have everything set to PCM and using Monster 1000 HDMI cables. Any suggestions? Thinking about selling my Pan and getting the Sammy today? Good deal on the Panny also.
