I guess it’s time to talk about these amps in terms of The Loudspeakers. In truth, I thought of these amps from the first time I thought about The Loudspeakers, to the point where I “built and tested” The Loudspeakers with these amps in my head before I so much as ordered any speaker parts. I already admitted that I was grateful (rather than surprised) when the MA 9S2s proved such a good match for The Loudspeakers, because, although I was not certain of a good match, I would not have gone forward with the project at all unless I +/-  expected acceptable results. I never expected ULF from The Loudspeakers, so I still cannot speak to this in terms of the amps’ capabilities. Fair to say, I think, not many amps can get serious Music from an 18” woofer. And I suspect the MA 9S2s could do “good ULF” with the right subs. I can say that The Loudspeakers driven by these amps are at least as Musical as any “4 box” speaker system I have ever heard, meaning 2 speakers and 2 amps. “Full Range Speakers” might be a pipe dream, but these amps have allowed me to get pretty close, and it is hard for me to talk about my version of The Loudspeakers without including these amps in the discussion.Stick out tongue>gt;

Paul, I find your reporting fascinating. I believe a lot of the success is due to the speakers being very "source tolerant". That means through efficiency, little dependency on amplifier damping factor. Through intelligent crossover design, little demand on the amplifier to compensate for phase anomalies or large impedance swings.

What it also means that in the sense that Romy actually uses the amplifiers to "voice" the system, this is not happening. The voicing of the speaker does not give you clues of what could be "if". Not needing to change is a wonderful state - especially for someone that followed that path. Perhaps you are now successful in regard to the Remedios "Low Maintenance" UseCase?
