I went to buy a Tyros 3 weeks ago. A salesman (who didn't have a Tyros) said that the 3000 is exactly the same in sound, and that the features on the Tyros weren't worth paying for (as has been said here.) I thought great! I'll save £800 and get built in speakers! But I wanted to be sure, so I went to Chappell who have both on demo. I played the same song, using the same pre-set beat, using the same earphones. When I played the Tyros, I thought the sound was amazing - it really inspired me. When I played the PSR3000 it sounded exactly like my PSR640, with some new sounds and beats. I wasn't going to pay £1000 for a keyboard that is basically the same as the one I got already. I brought the Tyros right there. The 3000 sounds tinny and 'keyboardy' compared to the Tyros. No question.
