Hi Chuck,
I have had my DC3Pro for about 3 years now. I don't know what the major
differences are, but I do know I'm glad that I went with the pro. I have
monitored the group since I got my pro and have heard many problems over the
years with all different disklaviers. Many of them related to the volume
when playing midi's from the net. I have never experienced any of these
problems. I'm not a concert pianist but my best friend is. He is trained
classical concert pianist at has a DC3. He loves to play my pro. We have
recorded him playing mine and he is amazed as the accuracy and clarity that
the pro records with. He is planning to trade his for a Pro model sometime
this year. Hope this helps.
