Love them - worth the money
I got an early demo pair of the Minis from Saturday Audio Exchange in Chicago, and I love them. They're worth every penny. I have them installed in my kitchen, where I end up listening to most of my music anyway, and am driving them with an NAD 326bee. (My living room setup has the PSB Imagine Ts and NAD 375bee. Love that too.)
The bass is amazing for speakers this size, and the midrange, in true PSB style, absolutely sings and lacks the fatigue I feel with my Paradigm Studio 10s (which, to be honest, are punchier on bass and treble.)
If you can afford them and need small speakers for a specialized application, you won't be disappointed.
