BTW, I have a Samick 5'7" Grand Piano with the Pianodisc system, in my living room. In head to head comparisons, playing Barry Douglas' Mussorgsky- Pictures At An Exhibition (which I have in both the Pianodisc version and redbook CD), the piano handily beats my Summits. Nothing like live music!! This Yamaha system looks spectactular. I wonder if they will be partnering with Sony to offer more "original" high-def recordings.
