Gato Perfect Symmetrical Amplification
A typical MOS-FET push-pull power output stage consists of
both positive and negative polarized transistors. Because
it is impossible to make two identically behaving transistors
with opposite polarization, small differences in the electri-
cal characteristics must be accepted. This compromise of
imperfection will create an asymmectrical amplification
with a different signature in the positive and in the nega-
tive signal response often resulting in audible distortion
and listening fatigue.
The multiple transistor circuits may offer great power
handling but returns an asymmetrical and smearing of the
time domain. In this "choir" of transistors all of them are
"singing" with a slightly different voice than its brothers and
sisters. Smearing the micro transients and disrupting the
To solve the problem of the "bad choir":
The Gato Audio TwinFET
The simplicity of the TwinFET technology offers perfect
time domain symmetry with a clean and clear over-
whelming sonic performance instantly noticed.
The Gato Audio TwinFET amplifier is named from the
design using two perfectly identical FET transistors that
ensure perfect sonic timing, almost unlimited power and
and a perfect symmetrical high voltage swing. The TwinFET
technology is sonically far superior to designs typically only
focused on delivering voltage and current - not a perfect
symmetrical time domain.
Vacuum tube amplifiers use identical tubes in the output.
Some tube amps are designed with a single tube for
positive swing and a single tube for negative swing. These
amps have some similarities to the TwinFET except for
To supply more power output tubes are paralleled. This
again creates a problem because of the difference between
the tubes in the choir. Tubes have a finite life and start to
deteriorate from the beginning. The problem is the
deterioration curve is not the same on each output tube.
The Gato AMP-150 = 150WPC $4995.00
In my opinion the AMP-150 is the best integrated made at
any price...Anyone who listens or owns one agrees. The
integrated AMP-150's separate preamplifier is built from
super low-noise, high-bandwidth parts. Special signal relays
are located close to the input connectors for a short signal
path rendering remarkably low levels of noise and
The separate amplifier section feaures a JFET input stage,
a separate power supply for the critical driver circuit and a
single set (two per channel TWIN FET) of unique high-power
MOSFET output devices (capable of 150 amps). The sound
of the ultimate tube amps without the fuss.
Heat, current and DC offset are under constant
surveillance by a microprocessor, protection circuit.
The Gato PWR-222 Mono Power Amplifier $9995.00
If you need more power (output 250 Watts each --- FET's
capable of 500 Amps) or the absolute in sonic performance,
look no further. It does not get any better than this no
matter what the price or claim is!
The AMP-150 and the PWR-222 are ready for a demonstration. You need to be ready, This will change everything you thought in the past.
