I had the Innersound I330 power amp paired with the Innersound Eros Mk 3.5 passive ESL's and the combination was pure bliss. I would highly recommend a used Innersound amp or one from Roger, especially if you own a difficult to drive electrostatic loudspeaker.
Sanders ESL Power Amp & Mono blocks
I would be interested to hear feedback from users of the Sanders amplifiers. In particular, why you chose this amp and what else you considered at the time? Further, did you also acquire Sanders Pre-amp or opt for another manufacturer? If another manufacturer who?
I have some power hungry full range planars (84dB sens) to feed.
