AUDIO-GD NFB-28.28 DAC ES9028Pro TCXO
DAC 32bit 384khz AMANERO I2S HDMI USB
Versatile, efficient, unmissable
The DAC NFB-28 from Audio-GD is back in 2017 with the new ESS Saber ES9028Pro chip and the Amanero latest generation USB interface.
This version of the NFB-28 incorporates the same new features as the NFB-1DAC, including: An ESS Saber ES9028Pro DAC, a better Saber implementation offering a shorter signal path, the ability to select hardware filters, DSD auto-detection (with switching noise-free switching), and disengagement of the preamplifier function (with a button on the back) for pure DAC use.
NFB est the acronym of 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 ES9028Pro allows you to manage 32Bit / 192kHz sources in SPDIF as well as USB, and juicethat at 384kHz in USB Amanero. In order to use the NFB-28 under Windows via its USB-B input on the back panel, you will first need to download the Driver Amanero Combo 384 AUDIO GD:"http://www.audio-gd.com/Pro/dac/Amanero/AmaneroEN.htm" target = "_ blank">Amanero Combo NFB-28 ES9028Pro driver.

32bit / 384kHz / DSD / DXD / TCXO / HDMI
The 100% discrete design of this DAC (no PDO) goes through three stages (voltage, 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 provide 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.
SABER ES9028PRO
This high fidelity DAC is equipped with the famous ESS ES9028Pro 32 bit / 384kHz. This conversion chipset is capable of reading High Definition formats from DSD to PCM with one of the best signal-to-noise ratios on the market (120dB real on XLR). 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 ES9028Pro to reproduce the highest levels of detail and dynamics on ESS SABER DACs.
