Hello
I have a PSR2000 and a Tyros. While the 2000 is terrific, they Tyros has more better sounds and most importantly to me is the tone is tremendously rich.
With my daily exposure to very expensive Lowrey home organs, my ear is always looking for the fullest, richest tone. The Tyros organ voices are really much better than the 2000 along with all the rest.
In short, I thought you couldn't beat the 2000 until I got the Tyros.
