Thanks for all of the great recommendations. I actually have a 1960's juke box at my cabin and listen to a lot of old stuff on the weekends. It has tubes and does sound better in mono than in stereo!
I think I may be leaning toward the horns just because a lot of the stuff was recorded in mono thru tube equipment. I did check out the Horn shoppe, but can these little things acually be that good? My listening room is 14x20 with 16' vaulted ceilings and a real open floor plan. Actually the best place to put speakers are in the corners so the horns may even produce some bass.
