I bought this Kawai CA701 as my first piano for home use. The quality is great, the keyboard has a very nice touch, and the sound is good, though not the same as an acoustic Kawai upright piano (my teacher has one, and I'm practicing on both now). For me, there is a big difference between a real piano and a digital one. I'm not saying a digital piano is bad-absolutely not. But it's different!
I tried adjusting some settings, but the sound in the C4-B4 range isn't loud enough. Some keys, when pressed slowly and lightly, don't produce any sound at all. It's not a fault, no, but if I gently touch the keys of a real piano, I still get a very soft, whisper-like sound. On the digital piano, however, it seems like there isn't enough force to activate the recorded sound.
Overall, I'm very happy with my new digital piano. It looks great, feels great, and the recorded sounds while playing are very pleasant.
I hope that with more experience and practice, I'll find the best way to play this instrument.
