Tube Amp Recommendation

I am looking for a tube amp, if possible, recommendation for driving a pair of Acoustat 44 electrostat speakers. The speakers drop down to nearly 1 ohm at 20hz, so this makes it pretty tough on any type of amp. I am try to keep the price under $1500. Also, I use a Quicksilver full function preamp; I think it's OK, but I'm always open for suggestions.

Thanks in advance

Although I'm not very experienced with tube equipment, I am aware that an OTL type amp may be the only tube-type design that can drive a load of that nature. The OTL designs use no output transformer, but instead have a cathode follower output tube so that they can drive lower-impedance loads with better stability & coupling. Joule Electra builds such a design; no doubt there are others as well.
Also refer to this thread "tube amp for a difficult load":
