I've owned, without me counting, probably eight or nine Guilds and the same number of Yairi's, all classical guitars. About ten or twelve years ago, I found a new teacher which in the nylon world is hard to do. I figured I would puff out my chest a little and bring my Martin 0028C nylon.
The teacher had a Yairi classical, this guy is a professional. I played a few songs for him and thought I did OK. Then, he played his Yairi which was a lower intermediate guitar. But, boy did that guitar sound out. I was floored. I went home, hopped on CL and found the same model out in OR or WA someplace, bought it. Now I'm happy. Never brought the Martin again, in fact I sold it shortly thereafter. I either brought my Guild Mark V or the Yairi to my lesson every other week.
I worked my way up the ladder of Yairi's and after seven or eight stops, I found a 95CYM Yairi professional. I love it. the steel string professionals are DYM plus a number. I believe it is hand made, but could be wrong. It is a great sounding guitar. I also have a Guild Mark VI. Those two are my babies. I don't think I'd be able to choose between them, although being USA made, I'd probably take the Mark VI. Both are in pristine condition.
My 2 cents
