Audio-GD NFB-11.38

The Audio-GD NFB returns with several notable evolutions. Its digital / analog conversion stage works now thanks to a ES9038Pro chip, which is close to the top of decoding technology for a compact and very efficient DAC. In its 11.38 version, the NFB receives a Femto crystal. The global system stability is thereby increased and it provides access to ever more impressive levels of accuracy in terms of details of the soundstage, stereo depth  and frequency balance.

More than ever, the NFB is a very versatile tool, which carries with precision and accuracy the functions of DAC, preamp and headphone amplifier. To complete the experience, it enjoys a double stage power-supply, multiple selectable digital filters and a MCU controller.

The NFB-11.38 embeds now a DAC ESS ES9038Pro for converting the digital signals into analog. This allows a sampling rate support output up to 32bit / 384kHz and a high-end S/N ratio of 120dB.

This change in chip also supports a broad dynamic range, capable of reaching 140dB.

Using a crystal Femto significantly reduces jitter (ultra-low jitter) and will significantly prevent the inaccuracies and parasites at the critical time of decoding by the ES9038 SABRE chip.

High stability in processing data that promotes the capabilities of the NFB 11.38 and allows it to achieve impressive sound clarity levels.

In addition to supporting the DSD / DXD and sample rates up to 32bit / 384kHz, the 11.38 NFB takes advantage of the technology NFB (No-Feedback) developed by Audio-GD on its ACSS stage.

It operates as a discrete preamp stage that is totally free of operational amplifiers and other gain stage. With this construction, the signal is processed with high purity without unnecessary coloring of the sound, making it an element of choice for High Fidelity usage.

Equipped with a USB interface Amanero Combo 384 rather than USB32, it offers both optimum performance and compatibility. It therefore supports sample rates up to 32bit / 384kHz and the DXD, and DSD64 DSD128 (DSD256 DSD512 and Windows) .Its design allows it to enjoy a very low jitter.

Warning, a driver is required to run Windows. Linux and MacOS operating systems will be automatically recognized.
