Suggestions for high efficiency speakers?

I attended the Capital Audiofest and thought the Audio Note room had the best sound to my ears. Another attendee from Florida had a copy of "A Night in Tunisia" and it sounded like you were sitting in Art Blakey's chair with his drums right there in front of you. I want that palpability, that "you are there" sound I think low watt amps and high efficiency speakers deliver better than any other combination.

A couple years ago I heard the DeVore 96s at the same show and loved their sound, anyone know of other speakers that give the same sensations?

My system is a SOTA Sapphire w Sumiko MMT and Zu-modified Denon 103 into an Art Audio Vinyl One phono pre into a Lamm LL2 Deluxe pre into an Art Audio Jota SET power amp and into Joseph RM25 sigs.
