If you look at the graph of frequency response of the ML-3 in the
Stereo Review article, you notice that it is hardly flat--there is
a broad, 1dB peak from 2khz to 20khz, centered aroung 10 khz, and
and the bass falls off by 1.25 dB at 20hz, starting at approx 100hz.

These sound like minor frequency aberrations, but they are psychoacoustically
significant in double-blind tests--the emphasis of the upper midrange and
high frequencies sounds subjectively "better" than a flat curve.  Given
equal power conditions, with all amps equalized to give a flat response,
I doubt that one could identify the ML-3 versus a standard Japanese amp.

Now, as Hirsch points out, it is entirely appropriate to admire such a
piece of technological overkill, even if its sound isn't quite flat.
It is built like a tank, all components are of the highest quality
(at $5400 they ought to be) and let's face it, even we non-golden ears
can appreciate a slight coloration of the sound.
