Hi Al,
You are correct, it does transition to class B to provide more power and SET amplifiers certainly aren't capable of a differential balanced circuit. I don't know why I overlooked those two glaring factors. What is fascinating is the reviewer (Mr. Dudley) said based purely on listening the 25 watt Shindo was so pleasing with the Shasha. You'd never imagine this outcome possible given the speaker's load demands. He did also find the 400 watt Electrocompaniet amplifier an excellent choice as well. Based on specifications alone the Shindo would ( justifiably so) be ruled out as a suitable amplifier candidate. Audio is such an intriguing endeavor.
