The sound is very impressive. My previous receiver was a Denon 3801. The main reason for the upgrade was power! I have a 20x20 Room. The new YPAO feature is absolutely awesome. It auto calibrates itself! I never cared for dsp settings on my Denon but the dsp's on this Yamaha are awesome. I can listen to DD 5.1 and add a Movie Theater DSP on top of that signal. I still need to get used to the Presence Speakers. I cannot tell if they make much of a difference when listening to the dsp's. I am going to test the THX Ultra 2 Sound setting tonight. I never really cared for THX, but we will see. Can anyone tell me how DTS 96/24 decoding sounds? I assume i need a 96/24 compatible DTS title.
