As a newcomer, I see lots of discussions regarding Nelson Pass'
designs, but frankly room heaters just won't do it for me when my long-term goal is to triamp an Ambisonic "surround" setup.
Might have been OK back in Seattle but I'd have to double my air conditioning here in the desert to be able to listen 8 months/year.
For years I've been curious if anyone has built and/or listened to the following amps:
1. Robert R. Cordell's design presented in an AES paper and IR app-note. Used Hawksford's error-correcting output stage.
2. Mark Alexander's current-feedback amp, either IGBT or MOSFET version.
3. "Clone" of the incredibly expensive/complicated Halcro amp
4. Any of Doug Self's designs -- the ultimate "objectivist" himself.
I'm looking for comments based on actual experiences.
