I agree with those who gig with the S950 and leave the Tyros 5 at home. That’s exactly what I do. Why can’t the T5, 6, 7, or whatever the name, weigh about like a PSR model? Maybe Yamaha feels like we’re getting more for the money with weight and larger dimensions. What exactly is in the electronics and sound components of the T5 over and above the S950 that adds to the weight and size? Maybe that’s a ploy of Yamaha to encourage players to purchase one of each.
