The fact is that few, if any, here at SZ are players of the caliber of Yamaha's demonstrators. 
And few, if any, of us here are programmers of the caliber that Yamaha use.
And few, if any, of us here are sound engineers of the caliber that Yamaha use.
And few, if any, of us here have PA's and live sound engineers of the caliber that Yamaha use.
But, mysteriously, everybody EXPECTS to sound as good as the Yamaha demos...  

What are you guys smoking?
