I suppose you're entitled to your opinion, Diki, but the improvement in the SA/SA2 sax over the sound in your G-70 is far more than just marginal.

I've played both instruments...no contest whatsoever.

You really haven't played a Tyros3 for any length of time, have you, because, since you profess to be such an expert in judging sound, I don't think you'd be saying it's "marginal" if you actually spent some time working with SA/SA2 and taking advantage of the phenomenal amount of expressiveness available to a skilled player.
