No speakers!?!?!?

I wouldn't call the PX-575R a head on contender with the YPG-625 if it doesn't have speakers. To me, that's the exciting thing about the 625 -- you can gig with it in a small hall and it weighs 40 lbs. Other keyboards in the sub 40 lbs category DO NOT HAVE ADEQUATE SPEAKERS, with the possible exception of the P70 which has only 10 sounds.

I searched the 575R features and specs for any mention of its speakers -- no dice. Yet it costs about the same as a YPG-625.

On the polyphony, the 575R gets 32 max, but for some tones, it's 10! That means if you dual up, it can be 5?

I think you're right that Casio is trying to compete with Yamaha. Maybe they're trying too hard.
