For what it's worth, I have audditioned the Harbeth shl5 (very nice) and the Harbeth Monitor 40, which I would own if I could afford it. I would say that the overall resolution of the radial driver is higher that that of the Spendors that I have owned, the SP100 and the Spendor 9/1, but they have the same natural sort of presentation that really allows you to stop thinking about the speakers. Vocals on both are great, and I have yet to hear a speaker personally that betters either of them.
