Gato Audio DIA-400 Integrated Amplifier / Digital Analogue Converter

The Gato Audio DIA-400 Integrated Amplifier with digital inputs is designed and built to a vision of combining technology, power, sonic performance, connectivity, versatility, stunning looks and compact design.

Class-D with smooth analogue music

The DIA-400 amplifier offers a state of the art Class-D output stage with dedicated and optimized switch mode power supplies. The multiple stage power amplifier is built around proven technology from International Rectifier, optimized with a precision high frequency oscillator and PWM modulator. A pair of precision switching MOS-FET transistors, with super low on-resistance ensures the high frequency switching is done perfectly and with as little loss as possible. The output filters are made from quality PP capacitors and low DCR coils, converting the high power PWM signals back into detailed and smooth analogue music.

More than just an Amp

The built-in D/A converter offers real high end performance, enabled by the use of a dedicated power supply, a balanced-drive Burr-Brown PCM1794 D/A converter, an optimized high bandwidth I/V converter, and an analogue stage with low-Q, low pass filters. All digital inputs are up-sampled to 24bit/192kHz. This D/A converter will upgrade any digital source - such as wired or wireless streaming from your computer or CD drive - to a high end level of detail and musical performance.

Versatility and Connectivity

We had our eye on versatility and connectivity when designing this amplifier. The DIA-400 offers not only a wide range of digital and analogue inputs, but also line outputs, a trigger signal for external power amplifiers, and a configurable home theatre input. The HT input can turn the amplifier into a fixed level power amplifier for use in a surround setup, without compromising the sonic performance.

"This rock solid integrated amp is a genuine high-end audio component that delivers impressive, super clean, full spectrum sound." "This sweet integrated amplifier with DAC reminds me of the old adage good things come in small packages. When referring to the Gato Audio DIA-400 this is certainly true."
