By the way, has anyone had a chance to listen to the "B&O" MS150?

It is a time-coherent design, or at least that is the claim made by B&O. I think B&O uses the term "Uni Phase" design, or basically it means to have zero phase shift and able to perform a proper step response, just like Thiel speakers. But instead of using first order filter as the Thiel’s, it uses LR2, or second order filters.
