I agree IMHO the PA900 can't really compete with the Yamaha Acoustic voices although the String Sections were pretty close. In other comparisons I've heard the BK-9 is also better than the PA900 in my opinion. The Bk-9 has a tighter less processed sound. But again I would have to give the nod to Yamaha for acoustic voices but the margin is closer with the BK-9.
