I am going to buy a new digital piano and I can not make up my mind between these two model. The P250 sounds wonderfully but it has the drawback of being very heavy. I am not a big man (the opposite) so to move it would be very difficult. I tried the new P90 and it sounded good, but it was difficult to compare as it was in another shop and I played it with an headphone that was a little bit crappy. The keyboard is very nice (no difference with P250) but the sounds were a little bit less real (for the piano sound) than the ones in P250. The dealer said that the P90 has the same sounds of the P250 but without the amplifier and the loudspeaker (that I do not need) and that it lacks some MIDI controls (I do not even know what MIDI is, so I imagine I will not miss them). Unfortunately it is not feasible a side-by-side comparaison. The only two shops around my little town have or the one or the other, and a new arrival is not scheduled. I thank you in advance for your help and comments Sincerely G.
