I don't know how much you can extrapolate from this, but as Islandmandan mentioned above, Kevin Hayes had been using various Tannoy models at the shows lately.
At the last CES he used the top of the line Tannoy Kingdom Royal speakers with his Statement stereo amp (450 Wt/Ch) and it sounded pretty good. I would imagine, the lesser VAC amplifiers to be a good match with your speakers, provided, they have adequate power to drive them. Don't let "high" sensitivity rating fool you.
