I used to have a vk200 driving Virgo's. Great combo. Excellent bass, good staging, smooth open top end. I then upgraded to a vk60. The vk60 was more open rich in the midrange, better depth, not quite as good on the extremes. The vk200 was deathly quiet. They are both good, but different. I liked the vk60 better. I'm more a of a tube fan.
