People buy Clavinova's because they want the look, feel, and sound of a nice Grand Piano without having to pay $30-$50K to get one.
I have been looking for that Spec but cannot find the ROM memory used on either board. The CP330 Piano would compare well to the 407. I believe they both use the best Yamaha has to offer.
