Thanks for sharing this.

It's quite close and all sound very good but I think but at a push I'd say the SX900 had the warmest fuller/cleaner sound, the S970 was the loudest/weightiest/punchiest and the Korg was a little bit on the light/thin side.

Who knows how he recorded it and what effects were used,
but all in all it was an interesting demo...
glad you had a chance to listen seems like no one else did.

I don't have to listen; I owned all of them!

Haha, I still have all 3 (that is if you count the S975 the same as the S970) which people have said they are identical. So then I still have all 3 !
