The P70 doesn't have accompaniment.It also doesn't have as many sounds.
Yup. And the P70 also has smaller speakers, fewer speakers, and no display. I didn't mean to question whether the YPG-625 was better than the P70. Only meant to question Yamaha's use of the English language.
The sentence: "The YPG-625 is Yamaha's first 88-key Graded Hammer System weighted action portable keyboard." is clearly false, which they should know. The P70 is their product!
You may find a lighter weighted action,but it won't have the quality of Yamaha's GH (Graded Hammer)which is considered the best by many pros.
As far as I know, the hammer action should be identical between the two. They are both Graded Hammer Standard action (GHS).
