DIA-250S High End  Integrated Amplifier/DAC
 
The Gato Audio DIA-250S is the school example of how to merge excellent sound quality, perfect design, profound electrical circuits and aptX Bluetooth technology.
 
S is for "Super"
 
– this brand new amplifier may look like the standard DIA-250 amplifier we introduced three years ago, but in fact we put more than a years work into improve every part of the DIA-250s already fantastic award winning performance. We changed and improved the electrical circuits and layouts in more than twenty ways, the most significant being:
 
Optimized mains filter
Improved general and local power supplies
New input stage
Improved output stage
New analogue stages in the D/A converter
Improved digital signal routing
Updated firmware
Improved connectors
Incorporated aptX Bluetooth module
 
More details, better micro dynamics and more "air" around the performing musicians. Everything is served with naturalness and a musicality normally reserved big expensive class A/B amplifiers - the result is stunning!
 
Class-D with smooth
analogue music
 
The DIA-250S 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 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-250S 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 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.
