Which piano series by John Heiczman is better? Recommend one

First of all, the higher the piano, the better the timbre and the more transparent the timbre will be. John Heiczman's piano is relatively good. Take the entry-level version of YS-200 as an example. For a piano with a small budget and the highest cost performance, the height is 123, the appearance is a classic black piano, and the configuration is still very high. If you want to be more advanced and excellent, you can choose YS-500, 125 height. If the demand reaches the performance level, you can choose YD- 128 to YD- 133. The soundboard cavity is larger, and the timbre will eventually reach the performance level. If the home is a big flat building, villa or mansion, the grand piano is the first choice. After all, most of us only buy a piano once in our lives, so why not buy what we want! John Heiczman has a series of high-end logs, which are handmade, which is more in line with modern people's pursuit of environmental protection and investment appreciation!
