Gato Audio AMP-150 Integrated Amplifier

The all new Gato Audio DIA-400S has been thoroughly updated compared to the standard DIA-400. We wanted to get the performance even closer to that of our AMP-150 integrated amplifier but keeping all the versatile features and even adding a high quality aptX Bluetooth receiver. The DIA-400S has not only become one of the best sounding Class-D amplifiers but also the most flexible available.


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

Even though the DIA-400S is a rather expensive amplifier, it dares to be compared directly to exotic Class-D amplifiers at twice or four times the price. It features the best Class-D amplification technology available and combined with our delicate analogue circuits - the result is absolutely world class sonic performance. The DIA-400S is recognizable by its clock like ring around the solid volume knob.

Our reference in Class-D amplification

The DIA-400S 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-400S 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.

Features:

  • 2x 400W@8ohm / 2x 800W@4ohm
  • Class D output stage
  • Built in 24bit/192kHz D/A converter with upsampling
  • Coax and asynchronous USB digital input up to 24bit/192kHz, optical up to 24bit/96kHz
  • aptX Bluetooth 4.0 receiver
  • Accepts digital streaming directly from Apple iPhone or iPad
  • Two unbalanced and one balanced inputs
  • Nonmagnetic enclosure
  • Direct function; enables use in home theater sytems
  • Designed, developed and build in Copenhagen, Denmark
