Not me as they're rather expensive for me. and I also don't have the space for them. I have owned the 602's and currently own the CM7's. My 602's held up well and I sold them to a lucky Agoner after 12 years of enjoyment. I didn't notice any issues with my kevlar drivers on the 602's but that doesn't mean it wasn't there. Maybe that's why I sold them. I'm sure if it happens with the mid drivers, it can happen with all the kevlar drivers in their lineup.
B&W and deteriorating Kevlar drivers
I have a pair of B&W 802N's purchased new when they first were introduced. Over time I had noticed a slight "card board" sound in the upper midrange that seem to grow over time. Just replaced the Kevlar midrange drivers and the distortion left........they need some break in time, but I think I solved the problem (not the cross overs). They certainly changed color over the years from yellow to almost orange. I would recommend the replacement of the midrange drivers if you have the original 800 series.
