The simplest answer is: 1.YA series and YU series are different in appearance and consistent in content.

that is to say, Yamaha YA series and YU series pianos seen in the domestic market, if the YU series and YA series with the same height are compared together (such as YU121DS and YA121CS), after the upper door panel is removed, the two pianos are the same, but the difference lies in the appearance. The upper door panel of YU series is composed of three pieces (there are two strip-shaped sound holes at the splicing position), just to make the sound louder.

2. The YA series and the YU series are only for the sales of different merchants in the same city.

Maybe some friends insist that YU series pianos are better than YA series pianos, and that YU series pianos belong to the middle and high-grade pianos of YAmaha pianos. Then we can give some examples:

1. We can compare the following pictures, and the appearance of Ya series pianos is the same as that of U series pianos. If the two sound holes of YU series pianos are really so important, why don't imported pianos make them like that?

2. Yamaha pianos all over the world are full-board, only YU series pianos are disconnected, and YU series pianos are only sold in China! The difference between YA series and YU series in Yamaha's official website is only the door panel. If there is a big difference, will YU series and YA series only differ from 5 yuan in price?

3. Compared with YA series pianos, YU series pianos have one disadvantage, that is, they are disconnected on the door panel, which will make dust and oil in the air more easily embedded in the disconnected gap, which is not conducive to piano maintenance!

But both of them are produced in China and in Xiaoshan, Hangzhou. I suggest you compare other brands more! Caesars Castle in Pearl River! Riethmuller in the Pearl River, since it is made in China, the Pearl River is definitely the first choice!
