The same pianos of the P series (there are three types of P-45, P-115, P-255 in active service), but the price difference is double (over 20,000 NT, more than 40,000), in fact, it should not be used for direct comparison, but P- 115 already sounds great, do I need to double the price of P-255?
First of all, they are all 88 keys of a standard piano, but the P-255 is 5cm wider and deeper, and 5kg heavier (11.8 vs 17.3kg). Original wooden tripods are optional, but not universal. P stands for Portable, which allows you to move to every corner of the house. The size is also convenient for you to put away or move to the car.
This is a big difference. P-115 is 7W, but P255's 15W obviously makes the sound fuller & richer.
P-115 uses YAMAHA standard GHS, but it has an extra layer of coating above the black keys than its YAMAHA piano. It is called [黒鍊マット仕上げ] in Japanese. P-255 uses GH ivory synthetic bond. It's closer to the real piano and heavier. In addition, if you turn off the volume and play the keyboard empty, the P115 has a louder mechanical sound, and the P255 is really quiet, not having mechanical joints, and it plays more smoothly. There is a big difference here.
Number of simultaneous voices
P-105 has 128, P-115 is upgraded to 192, and P-255 is 256. There is an oscillator in the back for each number of voices, but it shows the cost. If you can use multi-voice overlap, multi-track recording, the number of simultaneous voices is very important to you.
The P-115 has 14 tones, and the P-255 has 24. Of course, this is incomparable with the hundreds of thousands of tones in electronic synthesizers, but the purpose of the P series is to be a portalbe version of a real piano. The purpose is to use it as a piano. 24 timbres can provide more piano timbre options, and the string also adds a slow string to choose from.
The P-115 comes with a simple FC5 damper pedal. Most people will consider buying another sound and pedal, unlike the P-255, which is an upgraded FC4 pedal.
The innovative function of P-115 is to provide the function of sound boost. In fact, it is to increase the EQ of the middle part of the piano, and the piano sound will light up. It is very suitable to be used as a piano solo in the orchestra. P-255 directly has a small Mixer, you can directly adjust the low, mid, and high voices. For example, if you want to play bass, you can adjust the low voices up.
P-115 was launched in June this year, and P-255 was in October 2014. YAMAHA has an APP that allows you to control the panel on P-115, such as tone, drum rhythm, etc. P-255 does not.
P-115 is very suitable for beginners. It can be bought at a price of less than $20000 on the market, and it is very valuable in terms of function. Of course, if you progress to the musicalian level, you need P-255 to give you feedback on the keyboard and tone. The question is how fast you progress. If you are learning very fast and have made considerable progress in less than two years, then it seems a more cost-effective way to buy P-255 directly. If this piano is your amateur playmate, it won't be too much difference which one you buy, and you won't really feel that there is too much difference. It is simply a budget issue.
