More impressions:
1. Playing through Bose L1 Compacts - wow what a difference. The little S950 really sounds pretty good with the Bose Compacts.

2. For some reason the Roland styles sound much better with the S950 than they do with my Tyros 4.

3. Just about all the styles on the S950 were on the Tyros 3 and the Tyros 4 as far as I can tell and sound pretty much the same.

4. Drums have been improved but still fall way short of Korg's drums.
