Roland FP-90X has great sound, and I mainly used to practice with a headset to stay in good term with the neighbourhood :) .
I have some concerns with the quality of the one I purchased. In fact I had to return the first one because one key didn't move properly (B5). Thomann support was relatively efficient in sending me another piano, I noticed it wasn't in the original packaging (so not sure I really go a brand new piano), and then when I started to play I noticed that the same B5 key had a similar issue, however not as bad as the first one. I kept the piano as I needed to study (I am an early intermediate level student), but this key not moving smoothly is bothering me sometimes. Also from time to time, the whole sound go blank for a second, and then restart; not the worse when practicing it would be disastrous when doing a performance.
I like the sound, how it responds to the touch and pedal.
Overall a good Digital Piano, I just have mixed feeling because of my experience and a question mark regarding the quality of the one I got.
