Imagine that!
As far as I knew, the Tyros was always made from plastic.
To each his own, I suppose...use whatever works for you, Lee.
Meanwhile, I'll thoroughly enjoy playing my Yamaha...as I said one time before, we all know what kind of sound we want coming out of our speakers.
I like a smooth, balanced sound, polished and sweet...that's what Yamaha provides, and that's why I play one.
It's like Bruno123 who likes the Technics sound...he's willing to give up a few things to have the sound he finds most appealing to him.
I can forgo the allegedly "live" sounding drums of the Audya and be perfectly happy with a much more cohesive, and balanced sound of the Yamaha any day.
