High impedance is usually quite easy operation for an amplifier. Almost no current has to be delivered. Just keep the voltage proportional to the input signal!
The opposite however, to keep the voltage up even at high currents and a complex load, thats hard.

Thanks and I admit the obvious, total ignorance. But I was under the impression that the impedance curve on esl transducers is backwards. If the impedance rises to 15 ohms, then the 30.5 puts out much less than 30w,whereas the output doubles at low impedance. Is this not correct?

It´s also so that even the variable impedance curve the frequency responce is quite flat.
In the bass, close to the resonance frequency the impedance is going far up. This means that the efficiency of the speaker actually rises!

i think overal it is just to low on power. altrough my class D 50 watts can drive my esl63, not saying it sounds the best but i must admit i did not hear much difference between the class D and my 2x100watt 8 ohm amp witch can handle down to 2ohms. noise floor is higher that was easy to spot 🙂
My room is big and with a wall to wall carpet over cement. This makes it dead, hence the need for a little more power. No problem with the rogue pharaoh whatsoever. Feels stable and powerful.
