Since I last posted, I can add the Cube Audio Nenuphar Basis (Nenuphar full range driver supplemented by a powered woofer). To me, this system is MUCH better than the single driver Nenuphar system and at a not ultra crazy price. In the really high end range, I heard a recent custom build by Deja Vu Audio that sounds great--vintage Western Electric 713A driver and 32 horn for midrange, Fostex tweeter (current model), and vintage Goodman 18" woofer, modern parts crossover using Audio Note copper capacitors). This system sounds terrific when driven by Western Electric 124 amps (6L6 or 350B tubes).
