Good evening and compliments on the forum.
I wanted to ask for an opinion regarding the purchase of an upright piano for study. I have been taking private lessons for about 4 years now, and since I am advanced in my studies, I had decided to change pianos in view of preparing to enter a conservatory. Currently, I play on an old upright that belonged to my mother when she was a teenager (131 cm in height and 34 in depth) G.L. Nagel Heilbronn, though I do not know its age (the only thing I discovered searching on the internet is that this brand stopped producing pianos back in the 20s. Consequently, it is certainly at least 90 years old...).
I love its sound—not too powerful, full and clear, with deep lows and limpid highs. The problem is that being so old, the action no longer works perfectly and there are other little problems: the dampers do not lift completely or at all when I press the pedal, the hammers are a bit worn (from this characteristic I assume that, despite its age, it hasn't been played much, excluding the possibility that it was refurbished without my knowledge) and the strings are a bit rusty. Another point to clarify is the tuning; since I have never had it done (the last time my parents had it done was 16 years ago), I don't know if, once tuned, the piano would hold it.
Given the situation, I have decided to buy a new piano but... I have no idea where to start! I haven't had the chance to go looking for one yet, so I am turning to you. The only piano I tried (still 2 years ago) was a Yamaha U3, but I remember not being entirely convinced by it, although right now I don't remember its sound perfectly.
Taking into account the fact that I live in an apartment building, I would need a "silent" piano (the U3 I saw actually had the Silent system) and, given the dimensions of my house, not a grand piano.
The budget is 10,000 euros, at most a little more.
If there were a piano with a sound similar to mine, that would be the best.
What do you recommend?
