Apologies; it was Martin Colloms, not John Atkinson who made those measurements.
Bottom line is that more power does not necessarily translate into improved sound with the 2.4s. I failed to mention earlier that I have also owned Musical Fidelity's 250 wpc, Krell's 150 wpc and CJ CA200 185 wpc integrated amps with these same speakers and, by far, and to my ears, the CAV50 outperforms the other sonically with these same speakers. It simply provides that "ahhhh" factor much better than any of the others; I know I was hoping that either the CJ CA200 or the Krell integrated would be preffered, but such is not the case. What I also know is that the 2.4s are nowhere as diffcult to drive as Thiel's older models, such as my 6s, which I power with a Krell 400cx. The 2.4s are highly, and I emphasize, highly, revealing of the quality of the power feeding them.
