DIA-250 - Shopify
High End Integrated Amplifier / DAC
The Gato Audio DIA-250 Integrated Amplifier with digital inputs is designed and built
to a vision of combining technology, power, soni performance, connectivity, versatility,
stunning looks and compact design.
Class-D with smooth analogue music
The DIA-250 amplifier offers a state of the art Class-D ouput stage with dedicated and optimized switch
mode power supplies. The multiple stage power amplifier is built around proven technology for
mInternational Rectifier, optimized with a precision high frequency oscillator nad PWM modulator. A pair of
precision switchin MOS-FET transistors, with super low on-resistance ensures the high frequency swithching
is done perfectly and with as little loss as possible. The outut filters are made from quality PP capacitors and
low DCR coils, converting the high power PWM signals back into detailed and smoot analogue music.
More than just an Amp
The built-in D/A convertor 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 upsampled 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-250 offers not only a
wider range of digital and analogue inputs, but also line outputs, a trigger signal for external power
amplifiers, and a configurable home theater 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.
