The Virtue amps are characteristically very similar to the Red Wine amps, and from personal experience, they pair very well with anything from Zu.
There is a coherence and aliveness to the Zu lineup that drives long term satisfaction. This is particularly true regarding the Druid, Soul, and Definitions.
At the recent California Audio Show, only the JBL Everest and Magicos filled me with great longing, but those speakers are much more of course. No one's ever content in this hobby, but the Druids stayed in my system for 3 years while every other component was swapped out multiple times and I'm now waiting for the Soul Superfly to be delivered. There was, I have to confess, a brief 6 month fling with another speaker which made me regret the Druid sale almost immediately.
I expect that barring a serious lifestyle change (ie. winning the lottery), the Soul Superfly (which is known to be comprehensively better than the Druid) will be with me for a long time to come.
