Hello

I am almost buying my first grand piano

. Before taking the final decision I wanted to hear the opinon of somebody more expert than me.
Budget is around 20K (euros) and at the moment I tried Hoffman / Playel (2nd hand) / Yamaha and in all cases I can buy a 175 cm.
My choice is at the moment the Yamaha c2x... I think the sound is more equilibrate than the old series and the mechanics it seems quite good in my opinion. Furthermore I do not really trust second hand pianos... sound can be good but the structure, the mechanics can be not perfect due to humidity the piano have taken etc...
Does anyone experience on this piano? I play classical and I plan to study on it a lot
I have also a couple of question...
In regards of the silent. The piano seller is not recommending me to mount the silent system after the purchase because it ruin the piano over the year.... do you confirm that as well?
At the moment I have a kawai cs9 (digital) and an upright Petroff ... do you think is better to keep the digital without mounting or buying a piano with a silent system or keep the petroff and use the soft pedal (well I dont know how it is called in english...is the central one) to study?
Thanks a lot for in advance for the answers!!
