Generally, the Harbeth will sound more open and illuminating with certain tube amps. I have only listened to the Leben CS300 driving some Harbeth. In comparison most solid-state amps sound slightly darker/warmer.
However, if you listen to rock at moderate to high levels a solid state amp would be more suitable in my view. The bass slam and dynamics of the Harbeth are usually better if you feed the speakers with more current or power, and it is usually from solid-state designs.
