You've been given a ton of good recommendations and you're not in a hurry which is great. Since you can get down to this area I would suggest stopping by Deja Vu Audio in VA, they are the AN dealer running the room at CAF. In addition to AN speakers they also build their own hornspeakers so a good chance to compare and contrast.
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.
