DAC / Headphone Preamplifier / Amplifier Audio-GD NFB-27.38

A versatile and efficient HiFi device ...

This is the new version of the NFB-27, the NFB-27.38, with the qualities of the NFB-27 and MASTER 9. This version is the latest in the NFB family, which stands for "Non-Feedback" against reaction).

Non-Feedback is the technology used by Audio-GD so that it does not "color" the sound at the level of the electronics of the output stage, giving you a sound of professional neutrality.

Unique interior and connectivity

This device has a DAC SABER ES9038pro supporting the signals up to 32bit / 384kHz and DSD in USB, all thanks to the new asynchronous interface AMANERO 384 combo of the manufacturer. In order to use the AMANERO correctly, here are the indications of Audio-GD as well as the download link of the driver: Amanero Combo 384 USB Interface.

The DAC preamplifier NFB27.38 also has a potentiometer with switched resistors of the highest quality on 100 steps.

The NFB-27.38 has 8 inputs: XLR / RCA x2 / USB / Coaxial / BNC /I2S via HDMI / Toslink optics, alongside 3 analog inputs: XLR / RCA / RCA. Including the DAC and Preamplifier outputs: XLR / RCA, as well as the 4 outputs Headphones: 1x XLR 4 PIN (ACSS) / 2x XLR 3 PIN / 1x 6.35mm stereo jack.

Strengths and characteristics HIGH FIDELITY

32bit / 384kHz / DSD / DXD / PCM / TCXO / ES9038

The 100% symmetrical and discreet design of this converter is backed by 5 groups of Class A power supplies. 24K Gold Plated RCA Plugs as well as Nover (UK) capacitors have been specially manufactured on specifications audio-GD.

The NFB-27.38, in addition to all the rest, has a TCXO Audio-GD internal clock directly integrated into the system significantly lowering the jitter, as well as internal wiring designed entirely of OCC copper.

Acss Connectors

The ACSS analog output stage, which is a feature of AUDIO GD, reduces the signal with only one buffer stage and an original Dale (USA) resistor. This shorter signal path allows the ES9038Pro to reproduce the highest level of detail and dynamics on ESS SABER DACs.

Remote Control Metal

This NFB-27.38 is accompanied by its remote control metal, brushed aluminum finish. All the sobriety and class of Audio-GD stand out from this remote, as it is purified and functional. You will find 2 buttons to change your input sources, as well as 3 buttons to adjust the volume: Plus / Minus / Mute.

ES9038 DAC


This SABER ES9038 conversion chipset built into the NFB-27.38 is one of the first generation 32bit converters capable of reading high-definition signals up to 32bit / 384kHz, not forgetting the DSD and PCM files. It is recognized as one of the most efficient and effective converters. You can find all its detailed documentation on the official ESS website: ES9038Pro - Reference 32-bit Audio DAC.
