I confirmed at yodobashi-kamera store that LX9 (¥553,300 ~ ¥586,300-) has the same touch of an acoustic piano and its sound quality is far better than a Yamaha C3X grand piano. This LX6GP has all the same keyboard and similar functions. Because it's a digital piano, so you don't need any tuning. It has 10-year warranty too.
