Why Don't you hear more about Audio Physics Speakers??

I used to frequent a high end store called Sound II in North Dartmouth, MA. They sold Audio Physics speakers and the many times I heard them, they always sounded fantastic.  That’s all I know about them as at the time I-owned Vandersteen 2CE Signatures speakers so I wasn’t too interested in others.  However, whenever walking into the store, I was always greeted to the wonderful sounds of the Tempo speakers, driven by an early VAC amp and an RCM (I think) turntable.  The quality of the sound made you want to sit and listen.
