which tube mono blocks?


I run electrostatics that are 4Ohm @ 86dB. I currently use 200w Class A SS mono's. Which tube amps should I get to try?

Darkmoebius, just for the record, I stated that about **all** amplifiers, tube *or* transistor!
Thanks for setting the record straight, I had a feeling I was getting something wrong.
The best options have been mentioned Atma-Sphere MA2, Wolcotts, big VTLs; all will be costly...Cheers,

Canary Audio CA-160 monoblocks. I am using these to power Piegas, which is no small feat. These are powerful EL34 based amps that should do what you need.
