I owned a pair of Shearwater Hot Rods a long time ago. They sounded a little mellow in the room I had them in. They were placed well away from the side walls and I was sitting lower than the tweeter axis.
I listened to a pair of Thiels - not sure what model - but I felt the upper midrange / treble seemed accentuated.
Vandersteen speakers also follow a similar philosophy to Meadowlark and Thiel - first order crossover, time aligned drivers.
