AUDIO-GD NFB-28.38 DAC / Headphone Amp / Preamp 32bit / 384kHz ES9038Pro Silver

AUDIO-GD NFB-28.38 DAC ES9038Pro TCXO Silver

DAC 32bit 384khz AMANERO I2S HDMI USB

Versatile, efficient, unmissable

The Audio-GD DAC NFB-28.38 is back in 2017 with the new ESS Saber ES9038Pro chip and the Amanero latest generation USB interface. This version of the NFB-28.38 incorporates the same new features as the NFB-1.38 DAC, namely: An ESS Saber ES9038Pro DAC, a better Saber implementation offering a shorter signal path, the ability to select the hardware filters, a DSD auto-detection (with switching noise-free switching), and disengagement of the preamplifier function (with a button on the back) allowing pure DAC use. NFB is the acronym for "No Feedback" used by Audio-GD. This technology on the analog stages allows a great respect of the harmonics, without distortions, without digital hardness.

USB AMANERO and I2S HDMI

The integrated SABER ES9038Pro allows you to manage 32Bit / 192kHz sources in both SPDIF and USB, and up to 384kHz in USB Amanero. In order to use the NFB-28.38 in Windows via its inpute USB-B present on the back cover, you will first need to download the Driver Amanero Combo 384 AUDIO GD: Amanero Combo NFB-29 ES9028Pro driver

32bit / 384kHz / DSD / DXD / TCXO / HDMI

Thethe 100% discrete reception of this DAC (no PDO) passes through three stages (voltage current, low pass filter, buffer) with transistors without any capacitors on the audio path, supported by a class A power supply with a fast rise time capable of providing the necessary energy. Nover (UK) capacitors have been specially manufactured on Audio-GD specifications. The output transistors Toshiba and Hitachi have been manually paired. AUDIO GD use the best available components: Wima, Dale, ESS, Atmel.

TCXO - 100MHz

Usually the Audio-GD devices are equipped with standard 80MHz clocks, except this DAC Audio-GD NFB-28.38 includes the 100MHz TCXO Ultra Low Jitter option, perfectly associated with the ES9038. This TCXO (temperature compensated oscillator) clock is more accurate significantly lowering the Jitter.

SABER ES9038PRO

This high fidelity DAC is equipped with the famous ESS ES9038Pro 32 bit / 384kHz. This conversion chipset is capable of reading High Definition formats from DSD to PCM,one of the best signal-to-noise ratios on the market (120dB real). 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 shortest signal path allows the ES9038Pro to reproduce the highest levels of detail and dynamics on ESS SABER DACs.
