I am also a piano lover. I have bought three electric pianos, Casio px13, 33 and Yamaha p95.
my own is the latter two. The first 13 was bought for him from a friend.
My strong suggestion is not to consider Casio. There are too many minor faults. Although the price is lower, I am sorry for so much money. The only thing better than Yamaha is that the weight of the heavy hammer is larger and the handle is slightly heavier, but the difference is not big.
in terms of timbre, there is a big gap between the high-pitched sound source of Casio and the real steel, and it has a heavy electronic taste. More importantly, it has the problem of sustained sound (which has nothing to do with the pedal). The high-pitched sound decays very quickly, which is not found in any real steel, and has nothing to do with timbre. The reflection in music performance is that the bass can often cover the mood of the high-pitched part, and the prominence of the high-pitched part is weakened. Yamaha's piano timbre is sampled by Yamaha's own triangle. Although timbre restoration can't confuse electric steel with real steel, it is really good, basically the concept of digital camera and traditional camera.
From the keyboard point of view, the keyboard is the most unbearable thing for Casio. You must know this if you know it online. If you don't know it, you can search for problems such as "Casio keyboard is loose" and "Casio key noise". Both the Casio I bought and my friend bought had the problem of keyboard looseness within one month, that is, the key that I often played would be looser than other keys. After a long time, there would be a clatter noise, but the noise was tolerable. What was unbearable was that the feel of this key would be very different from other keys (in fact, it was only a little loose). Casio's keyboard problem is not a quality problem, even if it is loose, Casio's piano itself is intact, which will not affect its service life, but the design problem of Casio's keyboard. My friend took apart Casio's piano, and the loose reason was that the pressure of shaking left and right between keys was close to lubricating oil (key oil). With the loss of lubricating oil, the distance of shaking left and right would increase, which would hardly affect the service life, but even a little looseness would greatly affect the feel and effect of playing. Yamaha has completely surpassed Casio in this respect. Yamaha's keyboard will hardly feel different from the new piano unless it is in some extreme cases (for example, a piano that has been in a piano shop for several years), because the structure of Yamaha's keyboard is completely different from Casio's. After disassembly, there are special pressing parts for pressing between keys. Although they are all heavy hammers, the mechanical structure is very different. Yamaha's feel is slightly lighter, because the feel of Yamaha's big triangle is very light when Yamaha makes the big triangle, while the feel of Yamaha Electric Steel is imitation of Yamaha's big triangle, and the whole is actually very comfortable and comfortable. The professors I know who are younger in college music (for example, Mr. Chen Jin from Lanzhou University for Nationalities) all say that Yamaha Electric Steel has a feel and likes the middle and high end of Yamaha very much. Of course, the old professor only has real steel in his eyes.
Yamaha also attaches great importance to details. For example, when I use px33 timbre to superimpose the strings and the piano, the strings keep getting stronger with the pedal. As long as the pedal is stepped on, they will not weaken, and there is no way to show some techniques in real performance. However, Yamaha, when the piano is prolonged, the duet of the strings will gradually weaken when the fingers leave, and it will not affect the performance of the piano when it does not leave, which is very reasonable and greatly improved.
Yamaha is also doing a very good job in brand control. There may be one or two Yamaha agents in one place, but Casio's agents are everywhere. Casio mainly takes the market share route, while Yamaha is the brand route, which can be clearly seen from their low-end markets (especially the electronic organ market). Most of the music store owners I know don't want to do Yamaha business, because they earn too little, the genuine price is basically transparent, and Yamaha's agents all have Yamaha's sales price and inventory regulations. As long as you find out the agents in the purchase area on Yamaha official website, you can buy with confidence, and the after-sales are all integrated.
When you buy a piano, you must try it carefully in person, because any electronic musical instrument has a defective rate, and some people have bought Yamaha's defective products, but compared with Casio, it is far from the sky. The most convenient inspection method is to go to the customer service websites of the two companies to see the complaints, and the gap is very large. Casio is a blockbuster to reflect the problems, while Yamaha blockbuster is a consulting function.
What I said is almost catching up with the sales promotion. Hehe, although it is very encouraging, it is really my humble opinion. I hope I can help you.
