RE: Stacked Quad ESL57s

I'm repeating myself here, but will chime in to agree with Ralph. My Stax F83's have a very high impedance in the midrange (over 100 ohms), but falling impedance in both the bass and treble (around 4 ohms). They are also very very inefficient, rated at something like 76db/watt, and have the reputation as amplifier killers. But with an subwoofers to take care of the bass, an 80 watt OTL amplifiers drives them beautifully, with astonishing transients and very convincing dynamics.
