Introduction
With five digital including IIS/DSD and one analog stereo inputs, RCA stereo and XLR balanced outputs,
and decoding capability of PCM 384K, DSD256, the NuPrime AMG-DAC is a reference-class DAC with
natural, detailed, and expansive sound stage sound characteristics designed for studio professionals and
high-end audiophiles.
Preamp
In a modern high-end DAC, the preamp stage plays a prominent role in determining the sound qualify
and characteristics. AMG DAC preamp design features:
The sound is natural and relaxed with no hint of digital. Users can hear a very open sense of live
performance space with a focused sound field. The guitar and piano melody naturally scattered in the
listening space, making people relax and immerse themselves in it, transforming the stiff strings into
natural and smooth sounds.
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.
MUSES 8820 DAC IV Circuit Dual ESS DACs
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.
NuPrime Extension Port
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. The NuPrime Omnia WR-1,
BTR-HD, Stream Mini, and Stream Mini DAC wireless receivers have a micro-USB port that is
compatible this specification.
