I have to be very honest. I went to a local dealer to demo both the 802 Diamond and CM10. I bought my speakers from a friend and paid basically dealer cost. So the 802s were really what I wanted, such a unique polarizing design (which you know I adore). But, after auditioning with my preferred music types - metal and hard rock, fast percussion, sharp guitar and bass - I genuinely preferred the CM10s. I was shocked, but decided to save the expense and go with the "lower" line.
