For the purpose of Piano, I would say the Casio has it! The Yamaha piano is good but because of weaker speakers it has a less robust sound quality. If I run the Yamaha through a speaker system it sounds very good, but the Casio sounds great without the use of external speakers. I did do one thing in my store that has really sold the Casio Piano.......When you hit the button which has the grand piano on it, you always go to the piano, however, to my taste there is too much Reverb. So what I've done is to turn off the "dsp" light (this is the insert effect which is over and above a system reverb and chorus processor) and then I go to the system reverb and give it just a little reverb and store it at user location 600. Now, when someone comes into the store and tries the Casio I can show them a piano with a lot of reverb and my custom one with just a taste of reverb. Some think the stock piano has way to much reverb and I agree. Just having the ability to edit and store a new sound is a plus.
