Uncle Dave,
The keys on the PA60 are a little shorter than the PA80. This changes the feel a little bit. Some might prefer the shorter key because it responds with less key stroke.
The speakers are good. It's really hard to tell them apart. In the PA80 they use a woofer and a tweeter and on the PA60 is like a car stereo speaker with a woofer and the cone in the center for high frequencies. It's hard to tell them apart.
