That's interesting because the feedback I've been getting from some of the digital amps is that they don't do well with difficult loads. But maybe Spectron has a different approach.

The ML CLX are about $20k and large so they are not a consideration. I wouldn't mind finding a nice small ESL even without a bass module. Small enough I can sit them out of the way when not in use and drag out oaccasionally for some nice concertos or vocal. I love my current speakers but isn't variety the spice of life.
