Well it has been over a week since I have had the opportunity to "mosey on in" and I am surprised by the responses to a harmless question. My daughter is a pianist, she plays on a Young Chang, (the manufacture of Steinway's entry level pianos), so I have an ear for how a piano should sound. I have MANY piano CDs and most sound okay but I always figured that a speaker could never capture the resonance that the piano cabinet contributes to the instrument until I listened to this DVD. I am amazed at the sound "quality" of the piano over Diana's CD version. Maybe Soundhound is right, the timbre and dimentionality of the 5.1 may be accountable for this since the other recording variables for this should be the same. Thanks everyone for your thoughts, more are welcome. And yes JMS, she is a delight to watch. Not so much for her looks but for the obvious love she has for the music and the piano, I'm sure she had some say in how this recording was engineered.
