DAC 32bit 384khz USB AMANERO I2S RJ45 Symmetrical
The NFB-7.38 DAC is equipped with the latest ESS ES9038 saber component and Amanero's latest generation Asynchronous USB interface.
This new edition proposes a better implementation of the Saber proposing a path of the even shorter signal actually symmetrical and the possibility to select the hardware filters FIR PCM, DSD. The detection of different DSD formats (with switching without noise switching) is now automatic.
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.
This Audio-GD has 6 digital inputs: BNC / RCA / Coaxial SPDIF / Optical / USB AMANERO / I2S via RJ45. Alongside 3 analog outputs: XLR / RCA / ACSS.
The built-in ES9038 SABER allows you to manage 32Bit / 192kHz sources both in SPDIF and USB, and up to 384kHz in USB.In order to use the NFB-7.38 in Windows via its USB-B input on the back panel, you will first need to download the Driver Amanero Combo 384 AUDIO GD:= "http://audio-gd.com/Pro/dac/Amanero/AmaneroEN.htm" target = "_ blank">Amanero Combo driver.
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. This version 7.38 has three fully separated Class A power supplies for the digital, left and right stages for analog outputs.
The CNover (UK) dampers 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. The internal wiring is made of OCC copper.
This high-fidelity DAC NFB-7.38 is equipped with the famous ESS ES9038 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 shorter signal path allows the ES9038 to reproduce the highest level of detail and dynamics on the ESS SABER DACs.
