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?

What do you guys think of the Van Alstine Ultra 550? Can it compete with any of the above mentioned products?

Not exactly an apples-to-apples comparison what with the VA Ultra 550's output being power MOSFETs instead of tubes.
These: (http://www.audiogon.com/cgi-bin/cls.pl?ampstube&1232672742&/Antique-Sound-Lab-hurricane-mo) Some info: (http://www.vacuumtube.com/antiquesoundlabs.htm) BTW: The amps listed are not mine.
Oh well, its easy - look at one of Joule-Electra OTL monoblock (or AthmaSphere) you can afford and the end of it. If you never matched OTL with electrastatics then you never been in heaven!

Good Luck!
I would like to add another recommendation for Wolcott monoblocks...if I had to describe them in one word it would be "effortless".
