I thought that maybe the difference in the Pretender's song heard at Oneobgyn's house(expensive speakers, etc.) and my house(and other places) might have to do with my 8.5's driving very inefficient speakers. That would mean I needed to get the 9's. Anyway, after hearing that song elsewhere, I think the differences that I heard at Oneobgyn's house have to do with much more than speaker efficiency, or the ability of my 8.5's to drive inefficient speakers. BTW, nice job on your P-8. After audition, I bought it.
