@jhills IMHE, they all require plenty of power. The older SLs require more than newer models. Some of the smaller Maggies, a bit less than the larger ones, but 3.x and larger need a pretty good push to get their best out of them.
ESL63s were my first electrostatics too. They brought tears to my ears with small jazz, vocals and acoustic rock LPs, but on orchestras and prog rock I always felt like something was missing and I was listening to small speakers.
For me, SLs provide so much more dynamics and weight without sacrificing the strengths of the Quads. I'd say the Sanders do similar. My friend, a Philadelphia Orchestra pro, told me that his Maggie 20.7s don't hold a candle to my 30yr. old A3s; I agree. Cheers,
Spencer
