Aside from all the technological improvements on the 7000, I'd like to hear more about how it sounded. I realize a convention demo is not like playing it in one's home---and that the internal speakers where not used. However, from those in attendance, what was the first impression on hearing it? Was it a quantum leap beyond the 6500? Or, was it closer to what we're used to hearing with the 6000/6500? Were you shocked, surprised, astounded, or was it about what one would have expected? Were there noticeable or obvious improvements in sound quality?
