I just recently purchased a Casio CGP 700 and I have to say, the external speaker quality is not very good. It sounds very tinny, and cheap.
I've read that flipping the stand so that the speakers are facing outward and up against a wall gives it a richer sound. While this helped, it still sounds pretty bad. The piano sounds too much like it's coming from under me.
I've also noticed that the onboard speakers shutoff when the stand speakers are plugged in, which doesn't make sense to me. I would think that they would handle the high end. I wasn't too excited about the piano sounds either, the high end sounds too "pointy," and sounds really fake.
I had a Yamaha DGX 640, which sound richer, and was thinking of getting the 660, but decided to try the cgp 700. I might make a swap, since the DGX piano samples are much richer with better speaker quality. Does anyone agree with this? Or am I the only one for some reason. It seems like most people love the cgp 700, but I can't say I do.
Does anyone have any suggestions to improve my experience? Or should I should I just make the swap? Any input would be much apprectiated.
