There is no $1300 stage piano that even exists to compare to the $500 Casio trisensor. The $1000 P-155 has a better sound engine, speakers, and overall playing experience than the $500 casio. It feels and sounds like an actual upright acoustic. The lack of a 3rd sensor makes no difference whatsoever.
Typical...you completely ignore the subject at hand, and the recent commentary. Your statement that there isn't a $1300 "stage piano" to directly compare to Casio...this is relevant, how?
What, is this state of affairs somehow Casio's fault ??
Also, I have no idea why you have suddenly specified and focused upon a "stage piano" (slab style). I am not clear as to how that is germane to this discussion...especially since my original post concerned the Casio PX-850, and how (in my opinion) it's action was as good as DPs costing twice as much.
Of course, as you are an admitted beginner, I fully expect you have no appreciation for the difference between a two and three-sensor key system. In any event, I suspect that reproducing the action of an acoustic Upright
was not exactly the goal Yamaha was shooting for, with their P-155.
Furthermore, the fact that I am even bothering to reply to you, at all, speaks to the degree of inebriation I currently find myself in. It is a holiday, and the Patriots and Red Sox both had miraculous wins last night.
P.S. -- The Yamaha P-155 is a fine digital piano. I tried one before ultimately deciding on the Casio PX-850. I preferred the PX-850 for many reasons, the most important being quality of action, keyboard responsiveness, piano tones, as well as sound/speaker quality. My humble opinion, of course.
