Derek,
I too was impressed when I played my Tyros3 into the Bose system. Did you get to hear a Kn7000 played through the same system, when I did I knew I had found a near perfect match – awesome. People/musicians who have heard my Tyros3 and loved it were amazed when I played the Kn7000 through the system. The only word that seems to fit here is Reality.
