Rooze,
I see that you are familiar with Deja Vu Audio in Vienna, Virginia. They make custom horn systems that are pricey, but, they are worlds apart from Klipsch, Altec and the like. Deja Vu utilizes pretty exotic vintage drivers and currently manufactured drivers from Japan and Italy, and these systems are very different in sound from more common horn-based systems. If you are interested in horns, you should at least hear one of these custom systems.
By the way, I have a turntable like yours. I also have a Debut with vacuum clamp. I also have the Basis motor control unit. My tonearm is the Basis Vector arm. I have two cartridges, a Lyra Titan and a Transfiguration Orpheus L.
