DIY do it yourself tube amp kit

Darkmoebius, Yes, I spoke with Response. Sounds like they are very familar with the Hurricanes. I may check that out. I'm trying to keep my overall investment in my system lower than I have in the past. I've found that there are deminishing returns per dollar spent and am actually cutting back. Trying to get the best bang for the buck. Thanks for your correspondence.

I want to build a pair of Mono Block tube amps. I have a pair of ML Quest Z. What is your recommendation? I play my music loud and listen to all kinds of music. What do you think?

http://www.transcendentsound.com/ check out their OTL amps.

Are OTL's good with low impedence electrostats?

At the crossover region of 125Hz, I think those speakers were known to drop down into the 2-3 ohm range. Not an easy load, at all.
