The Tyros sounds are awesome but I don't think you'll lose a lot in that department at all by going with the PA80 if that's what you decide to do. I'll put it another way. The Tyros is going to be my next arranger purchase unless something else appears on the horizon that I like better ( very unlikely ), but I wouldn't give up my PA80 if that's what it took for me to get one. There are a few sounds I've been able to make with it ( via layering with performance mode and editing of the individual patches ) that I haven;t been able to replicate in my Motif, my soft synths, or my samplers. I am not willing to part with it for that reason alone.

If I had the Tyros, I'd likely say the same thing if I was looking to get a PA80. I wouldn't want to give it up to get the PA80. Either board is an excellent choice. Happy Hunting and enjoy.
