I tried for years to get the V MkII's to sing with a variety of components. I actually upgraded those speakers to above the Circe level with all new Alon alnico drivers, internal wiring, and a pair of Carl's outboard crossovers that according to Carl "contain more expensive components and are better than the Circe crossover." It just wouldn't happen for me, even when using a tubed preamp. They simply sound better with tubes, and I didn't want to go to a tubed amp. They also like power. I would suggest a tubed amp of at least 100 wpc (more would be better), and probably a tubed preamp also. As a hint, I believe I read that Carl likes the ASL Hurricanes.
I finally sold my pair of V's to achieve better dynamics in the midrange/mid-bass region, and a better mid-bass to bass transition. The V's caused a distinct mid-bass hump in two very different rooms I used them in. Carl began using two bass drivers in the Viper (I believe with staggered crossover frequencies) to remedy that issue. Reactions to the Alon/Nola speakers seem to be that users either love them, or prefer a different type of sound. The latest review in TAS of the Viper Reference explains the sound pretty good, and still applies to the sound of the V's.
Finally, I find Mingles' quote from Carl interesting since Black Orpheus uses a different connector for the bass run than for the other two runs, but I am sure it is voiced for the speaker. A used set of those should be inexpensive and should work fine. Good luck.
