SOUND (Japan), 30th
LAMM INDUSTRIES, INC. is
an American up-and-coming amplifier maker, which was established three
years ago. The number of products is limited but the company's M1.1
amp earns good reputation in the American market. It is largely due to
the designing and manufacturing policy set by the founder of the
company, Mr. Vladimir Shushurin, who is also an experienced amplifier
designer. His policy is: pertinent circuit design, careful selection
of high quality parts, and attentive assembly. From another
perspective, the company's popularity is due to its devotion to the
basics of amplifier making. It is clear that such approach generates
power to support the value of the company.
The company's top models
are the new productions that we want to pay attention to. There are
two of them: L1 preamp and M1.1 monaural power amp. Both are
handcrafted with highest quality selected parts. The L1 pursues the
natural quality of the sound and expressive power. The principle in
designing the L1 is class A operation, no overall feedback, perfect
topology management, and sophisticated and elegant design.
In addition, you can't
miss that the L1 employs MOS-FETs which are conscientiously selected
with special care, and that it is equipped with high-performance
voltage regulator that uses vacuum tubes in the power supply section.
These methods are employed to achieve the reliable operation and high
quality of the sound.
In terms of function, the
main features are 5 inputs, balanced and single-ended outputs, and a
phase switch for the output signal.
The M1.1 pursues the
reproduction of the rich soundstage in which even the subtlest
information about space is vividly captured. Also, its highlight is a
highly reliable design which maintains the stability of the unit when
low impedances are applied. In fact, an output of 300 Watts continuous
at 1 Ohm (100 Watts at 8/4 Ohms) proves the reliability. The factors
that contribute to such high performance are pure A class circuits,
high-speed power MOS-FETs, and the hybrid design employing 6922 vacuum
tube in the second stage. Needless to say, the best match for the M1.1
is the L1 preamp, which was mentioned earlier. The extensive appeal is
that we can expect the realistic reproduction of the deep soundstage.
