Love the base Meridian, the midrange separation is superb. I have a Bose in my 2013 Boxster and the Meridian is quite a bit better. The Bose has a glary midrange that causes listener fatigue. Haven't heard the high end Meridian but imagine it's superb. B&O is known more for style than sound, I heard one in an Audi S4 and it seemed pretty average although I only heard it briefly. Could be different after break-in.
