    Amps stable down to 1ohm or below...

    For difficult impedance dip speakers like Martin Logan and some other electrostatic speakers, what are some amps that are stable down to 1ohm (or below)?

    I would assume amps with a Bipolar output stage are going to have the edge over MOSFET/JFET output stages.

    Iím guessing a few are:

    * Gryphon
    * Luxman
    * Accuphase
    * Soulution
    * CH
    * Bryston
    * DíAg
    * SimAudio??

    Any others come to mind?

    Class D and Tube amps need not apply?

    Possibly the Sanders Sound Systems ESL and Magtech amps? Designed for, but not limited to, electrostatic speakers.
