Believe it or not, I've seen a Rogue Audio Cronus Magnum III very credibly drive a pair of E-SEs. In triode mode, where it's only putting out about 65 watts per channel.
Surprised the heck out of me, and pretty much everyone else that's heard it, but it did it. Really good sound.
Yes, I would usually want to use at least 100w/ch on those- preferably a bit more- but in a reasonably small room, they can do wonderful things on less power.
And, actually- they're less unmerciful to recording quality, than the similarly priced Magico A5 or the Acora SRC-1. The E-SE speakers are reasonably forgiving, compared to a lot of stuff in that performance class- without giving up resolution, tonal balance and speed.
