DUAL ES9038 PRO DAC
The DAC NFB-27.77 is equipped with two ES9038PROs, the latest ESS ES9038 high-end saber component, an FPGA processor and the Amanero latest generation asynchronous USB interface.
Implementing 2 DAC ES9038PRO instead of one, in addition to increasing the signal-to-noise ratio, allows dual Mono Pur work and a wider and more precise sound stage.
The FPGA (Field-Programmable Gate Array) processor used is the same as used in very high-end DACs, such as the popular ROCKNA WAVEDREAM DAC. Your DAC NFB-27-77 can always be updated at the firmware level, and therefore never be obsolete.
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.
PCM & DSD SUPPORT
This unit has two ES9038pro SABER DACs supporting up to 32bit signals/ 384kHz and DSD in USB, all thanks to the new asynchronous AMANERO 384 combo interface 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.
ROBUST PRE- HEADPHONE AMPLIFIER
The DAC preamplifier NFB27.77 also has a potentiometer with switched resistors of the highest quality on 100 stages.
The NFB-27.77 has 8 inputs: XLR / RCA x2 / USB / Coaxial / BNC / I2S via HDMI / Toslink optics, along with 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.
This SABER ES9038 conversion chipset built into the NFB-27.77 is one of the first generation 32bit converters capable of reading high-definition signals up to 32bit / 384kHz, not forgetting 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 website of ESS: ES9038Pro – Reference 32-bit Audio DAC.
ACSS SIGNAL LINK
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
