I am getting a vibration that may or may not be from the speaker - it sounds almost like it is the casing vibrating. Very inconconsistent, short duration, quiet. Listeners don't hear it, but I do. Produced by bass notes on grand pianos - below middle C. Not sure whether to return unit and try another.

I've had mine a week now. Love it! It has a lot of musical color. Mostly play the #1 piano sample. Hard to stop playing it. The only thing I'm concerned about is a non consistent sense of vibration on the left side as I face the keyboard, when bass notes somewhere lower that Middle C are played. Not consistent with single notes or chords. Its not that long or loud. My spouse cannot hear it. It doesn't quite sound like it is coming through the speakers - more the body of the unit - I am not sure if all units present this way. I have the keyboard on an x stand and tested it under carpet this morning. That seemed to eliminate some of the vibration. But I am still hearing something. A previous poster mentioned something about speaker vibrations that seemed authentic to him as part of grand piano sound. Some of the sounds don't seem to produce whatever this is I'm hearing. I hate to go back to GC and start getting in some crazy thing of trying another unit. Am trying to find out what other owners are experiencing. I love the keyboard. It is stimulating my creativity and expression. As soon as I sat down and began to play it, I could feel that happening. I had been looking at the Yamaha 105. I think its speakers are better, but its touch and sound are not. The sound is Yamaha - kind of plain vanilla. Am hoping for helpful feedback from you forum users. I also am waiting for a call back from Casio tech about this issue to see if they recommend trying another unit. Thanks for any help you can give me.
