I think what you have to realize is when Yamaha and "company" do these elaborate demos of their keyboards, their team of sound engineers and stage men are all professionals of long standing for the most part, and as such, are experts in their field and know what they're doing. They also have some of the best equipment in the known universe at which to make their keyboards sound brilliantly fabulous; including artists like Peter Baartmans with his shear brilliance on the keys themselves. So what?? Well.., if you have a similar Sound System setup as what Yamaha has when they demo a particular keyboard (in this case a Tyros3), then your Tyros3 will also sound similar in its sound output as what you would hear in the demo - in this case Peter Baartmans demo of a T3.

Those makeshift wannabe factory sound system speakers sold for the Tyros/2/3 do NOT do the Tyros3 justice no matter how you slice and dice (adjust) them. You need a "professional" set of PRO Audio speakers (and an excellent subwoofer for extended Bass, in my opinion) to really make the Tyros3 (or any other respectable keyboard) truly shine. It also helps if you, the player of the instrument, can help make it shine too. The actual keyboardist's playing ability is, in my estimation, at least 75% of the equation when it comes to making a keyboard really sparkle and shine. Of course, the sounds emanating from the keyboard itself are a big determining factor as well. You need to have a trumpet sound like a trumpet, a trombone to sound like a trombone, an AC.Piano voice to sound like a real acoustical Grand, etc. A brilliant player will be able to put those "potentially" excellent sounds to their best use though, of course.

Best,
