Do Pianos Sound Better With Age?

On the contrary unlike some instruments where it take some breaking into to get the best sound. The performance of a piano over time is determined by how much maintenance it has received after years of use. If the owner keeps it tuned on a regular basis and keeps it clean, then the piano will continue to have a great and rich sound as it ages. For references you can take a Car for example: If you care and maintain the car for many years it will eventually break down and need repair or even a whole make over. Same can be said about pianos, parts wear out and eventually need to be replaced. But to answer the question, NO, piano do no sound better with age, they can only produce good quality sound with proper care and maintenance.
