You are the third person I heard from today (got two emails earlier) that has not only played the Tyros5, but has also said what you did...the sound is much better than Tyros4.

I won't get to play one (a Tyros5-76) for a few weeks, and since I have a Tyros4 I'm going to compare them side by side...through the same speaker system.

Thanks for your review, Ron...you sound like you were very impressed.
