Thanks for the "Live" demos. Very impressive. IMHO, they sound much better through headphones with a "binaural" ambiance. BTW, I could only download the first three files from friedhelgoetz.com - hopefully the site is only temporarily down.

RE: Built-in speakers. Certainly a matter of personal preference, but my vote is for external monitors. I use a pair of Mackie HR824s which I dearly love and which can deliver loud yet very accurate sound. I played the factory MP3s through the Mackies last night and was amazed by how great the Tyros sounds!
