At one point, I was using at BAT VK-60 with my Super HL-5's. Listening to mostly rock, the Harbeths were likely not my best choice to begin with, but they sounded good so I kept them for years; still have them though I'm using other speakers now that are more appropriate to the kind of music I listen to.
With the VK-60, they were even less 'rock and roll' speakers but had beautiful midrange. I've since replaced that with an MSB S-200 power amp and a Herron Audio tube preamp; that made the Harbeths more to my liking....
