Anyone play a PRS with 57/08 Narrowfield Pups?

These appear to use the same logic (if not technology) as Leo's Cavalier and X body Interceptor pickups. Anyone know anything about them, give them a listen as all?

I played a PRS with those pickups and I really liked it. The guitar, tone, playability. I am a big time PRS fan but just didn't have the cash for a new PRS at the time but it is on my short list.

I would think if the pups are even with the rings they wouldn't need to be lowered, but maybe I am wrong, and someone else can give you some better input!!
