Just got back from the rehearsal. The sx900 really came on its own today. The choir leader was constantly complimenting me on the better sound from the new keyboard. Especially the new speakers help a lot. Quite loud but not distorted. Everything sounded well balanced and rounded. Mostly played the pianos, trumpets and strings with one or 2 songs with lead guitar. Sounds fantastic. Very very happy with the sx900 for now. More updates to follow.
