Fujioka: This one is a relatively
large monoblock, but it operates in pure class A
mode and generates 100 Watts at 8 (4) Ohms. In
addition, it has a "load selector"
switch for adjusting speaker load impedance.
Fukuda: It is a hybrid power
amplifier. It's got a magnificent response to
lower impedances with a switch that allows the
amp to run 200 Watts at 2 Ohms and 300 Watts at 1
Ohm. The expression of the sound is exceedingly
pure and neutral, as well as spacious and
elegant. I think this is a high quality amp which
is capable of very precise expression.
Fujioka: To tell you the truth,
there are many 100-Watt amplifiers by Japanese
lesser manufacturers. However, we can't evaluate
this one just in terms of generating power. This
amp's speaker driving capability is outstanding.
It has a wide enough frequency response and its
dynamic range is unbelievable for a 100-Watt
amplifier. Actually, all the 100-Watt amplifiers
should have such high driving capability as the
M1.1, and in that sense, we can call this one a
real 100-Watt amp. The amp's capacity to
reproduce the lowest frequencies is unlimited,
which allows the amplifier to maintain the tonal
balance during reproduction of even the lowest
possible frequencies. MOS type transistors
usually don't allow to reach this far into the
lower frequencies. Their range stays rather high
and produces a slightly lighter sound. But the
M1.1 fully reaches the lowest level and has a
capacity to go much further toward the low end.
This power amp gives quite a favorable
impression. I would say that this piece of
equipment is worth its price.
Fukuda: As far as the lower end is
concerned, energy density is tight and spacious.
The amp's high driving power results in a damping
sufficient at the lower range and also makes jazz
sound remarkably real. On the other hand, the
high end stretches distinctively and clearly, and
I was particularly impressed with the amp's high
signal-to-noise ratio. I would say this is a good
Fujioka: Let me point out one more
thing that fascinates me -- the midrange. Listen
carefully to the midrange of piano or voice, and
you can hear its outstanding quick response,
probably because of its use of vacuum tube as
part of the front end. Incoming signals turn into
music right away. Such response speed is
absolutely marvelous. It can create good
