I have a P-250. Does anyone think there is differencebewteen the CP300 and P-250?
Yes, there is a difference. There are more features on the CP300, which is obvious reading the specs. The sample size is much bigger in the CP300. I think the 300 is more realistic, and reminds me more of an un-miked piano in a nice room.
I think I still prefer the P-250. It seems to have more "punch" playing live. The two actions are very close, but a noticible difference. I am more used to the P250, but the CP300 seems a little better at times.
