NuPrime AMG DAC

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:
Output stage voltage amplification employing all discrete components.
Output stage current amplification utilising a high-speed amplifier with complete discrete components.

“Current transmitter” has no negative feedback amplifier.
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.

Other notable features:
Muses 72320 highly linear volume control.
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.The NuPrime Omnia WR-1, WR-2, BTR-HD, Stream Mini, and Stream Mini DAC wireless receivers have a micro USB port that is compatible this specification. This allow a standard off-the-shelf USB-A to micro USB cable to be used for power for the receiver as well as wireless audio data transfer in S/PDIF format.
