The PWR-222 features a 700W super low noise torodial power transformer, 44.000uF of RIFA capacitors, two 500amp MOS-FETS and WBT NexGen terminals. The super low noise input stage and the carefully optimized PCB design enables a S/N ratio of more than 115dB and a bandwidth of far beyond 100kHz. It is the culmination of development work started back in 2008 with the AMP-150 integrated amplifier and the perfect partner for the Gato Audio PRD-3S preamplifier.

The Gato Audio TwinFET technology has been developed to counter problems and compromises that are present in the majority of power amplifiers. TwinFET circuit solves these electrical and sonic problems at the point where they are created, thereby avoiding adding compromising correctional circuits and components. This is the basic reason why you only will find two output transistors in the PWR-222s output stage, one for the positive and one for the negative part of a sine wave, nothing more, nothing less.

The Gato Audio TwinFET push-pull technology is a unique way to create audio amplifiers. It has been developed to counter two major problems in high power MOS-FET power amplifiers and proves superior in sonic performance. The Gato Audio TwinFET technology features only two but identical and perfectly matched transistors with same polarizing in a push pull coupling. The TwinFET technology offers a perfectly symmetrical sine wave reproduction and uncompromised natural audio performance.

The mechanical dial display has three settings; to act as a VU meter, indicating output and clipping level, to show the current temperature of the amplifier or to be turned off completely. The PWR-222 has balanced and unbalanced input, nonmagnetic enclosure, it can deliver 250W@8ohm / 450W@4ohm, requency response is 20 Hz-20 kHz - 0.1 dB, and 2 Hz-100 kHz - 3 dB, and total harmonic distortion < 0,003%. The final verdict? Well, if you didn't try this Danish miracle, you can't call yourself an audiophile.
