Good choices kennyc. I’ve heard the Voxativ fieldcoil in another system and it is quite good. I have heard, and liked very much, Pure Audio Project speakers with the wooden horn and coaxial driver options, but not with the Voxativ. I share your interest in hearing it with the Voxativ fieldcoil. There is yet another Voxativ fieldcoil that costs $60 k per pair.
I would also like to here the AER backloaded horn single driver system with their $60 k drivers. This is like a Charney Audio system on steroids.
G.I.P. Laboratories makes some giant horn systems and fieldcoil Western Electric drivers to match. I’ve heard their drivers but not their horns. The drivers are very good, but some are crazy expensive (e.g., $60 k for a pair of tweeters).
I would like to hear in my own system the Lyra Connoisseur phono stage; I heard it in a system at a show and the system sounded really good.
