That sounds awesome. I want in!
It's funny, with my old system I first picked the speakers (Magnepan MMG) and built everything around that until I realized that since they're so inefficient and require a beefy power amp, I can't do any real isolation from the mains. In my experience, the power source is ultra-critical and a noisy one will render everything else crap. I've tried every type of power conditioning except batteries and a regenerator, and neither of those are possible with an amp that can do the MMG's justice. That was my first real attempt at building a good system. This time I'm starting from the power source and building everything around that. Experience rules. :)
Specifically what would you suggest for battery-powered amp and horn speakers to start out? Say, less than $3K?
Follow Ups:
I built 2 gain clones either I wasn't good enough or they where not good enough. My little Chinese custom tripath amps beat them real easy. As did any of my tube amps. I found the gain clones where happier with SS speakers. IE current drive speakers as apposed to the tripaths that die quick when asked for current mine are similar to a strong 300b in power and drive. They love hi impedance hi efficiency loads. I want to try kit hiraraga class A amps someday.
.
Any amp that can drive the MMG's with enough power can't be put onto batteries and it's debatable whether or not a regenerator would be up to the task. A regenerator doesn't provide the real isolation from mains that batteries do though.
I'm talking isolation tranny, why not use that?. I have a 20A
unit, so that should be way more than enough.
I've tried Tripp Lite and BPT personally.
Hmmm, I don't see how noise can make it through the tranny,
since it's tunes to 50/60 Hz. Maybe an engineer can tell us.
