The AMG DAC uses dual ESS DACs with discrete Class-A transistors for natural, detailed, and expansive sound stage sound characteristics. With five digital including IIS/DSD and one analog stereo input, RCA stereo, and XLR balanced outputs, and decoding capability of PCM 384K, DSD256, the NuPrime AMG-DAC is a reference-class DAC designed for studio professionals and high-end audiophiles.


In a modern high-end DAC, the preamp stage plays a prominent role in determining the sound quality and characteristics. AMG DAC preamp features the following designs that gives it a natural, relaxed and analog sound:

  • Output stage voltage amplification employing all discrete components.
  • Output stage current amplification utilizing a high-speed amplifier design.
  • “Current transmitter” has no negative feedback amplifier.

The Heart

As the heart of an audio system, the AMG-DAC supports an extensive number of inputs and formats. Dual ESS Technology 32-bit audio DAC ESS9038Q2M independently decode left and right channels improve channel separation and reducing overall noise. The Vishay professional film MELF resistors provide excellent sound quality.

Other notable features:

  • Muses 72320 volume control.
  • NuPrime SRC IC chip (co-developed with IC vendor) provides DSP processing where Input signals are up-sampled to megahertz before down converted to the targeted sampling rate with ultra-low jitter and distortion.
  • Extension port for Bluetooth receiver and WiFi audio streamer (optional).
  • Full microprocessor control with memory retention.
  • Supports DSD native playback by ASIO2.1 and DoP method.
  • Ultra- low-noise JFETs in the input stage for the lowest possible noise floor.
  • Individually adjustable volume on each input for precise level matching of sources.
  • Asynchronous transfer mode.

Using Bluetooth and WiFi Audio Receivers and Dongles

NuPrime defined an USB Type-A port to carry S/PDIF data and 5V power for connecting to external wireless audio receiver using just one standard USB cable.
