Hi,
I've tested several of them during Frankfurt Messe and one of the most natural sounding is Korg, or better the new line of Korg pianos.
I understand from some rumors that starting from SP250 and with the new C line (320-520-720) they have:
- new keybed (good for my taste, and with good feeling)
- new samples (a good and very natural sound).
It was a surprise for me, being a Pa1X owner but never satisfied with the Korg digital piano line (too poor/thin and unnaturally bright), finding these models. I strongly suggest you to check them out, especially if you play classical music.
Other comments regarding other brands top models:
- Yamaha: good sound, still a little too bright for my taste, good keybed.
- Casio: not so bad, but cheap construction (at the end it's Casio ....), keybed so and so.
- Kawai: good sound, a little too bright, the keybed is probably the best.
- Roland: a little step under Yamaha and Kawai, but the sound quality is much better than previous models, good keybed.
The competitors are really close and at the end what I like in the Korgies is that there is no emphasis in the high frequencies that others usually use to cut the mix, and especially played alone (sorry no choice to test it with a band at Messe) it's soooooo close to a traditional grand in IMHO.
Don't rely too much on specs, it's mainly the sound and keybed that make your choice.
Cheers.
