About NADAC-D

Native True 1-bit technology

A TRUE TECHNOLOGY BREAKTHROUGH

NADAC-D offers True 1-bit decoding for the first time. Mainstream HiFi decoders on the market generally use two types of technologies: the first is to directly use commercially available DAC ICs, which are audio digital-to-analog converter chips, such as AKM, ESS, and CS products. The second is to use an FPGA/CPLD circuit with discrete components, which is an FPGA/CPLD based Discrete DAC.

The technical specifications of the commercially available AKM/ESS/CS products are good, but their integrated circuit designs are typically treated as “industrial products” that cannot achieve the ultimate performance due to cost and semiconductor technology limitations. There will always be a balance of performance and cost and it is understandable that the end product has to appeal to a wide audience.

On the other hand, using the FPGA/CPLD discrete component scheme can often use powerful high-density logic chips regardless of cost. However, when it comes to converting into analog signals, some low-density but high-performance logic circuits suitable for audio applications are required. The problem is that companies that make these types of ICs will not develop “discrete chips” specifically for the HiFi industry, ending up with the same limitations as the previous solution.

The NADAC-D, Native Sound True 1-bit DAC overcomes this limitation. First, we chose a True 1-bit solution, but this solution is highly dependent on hardware performance, such as clock quality, power supply quality, and high-quality components that match it. Therefore, NADAC-D directly chose to have professional IC manufacturers customize Audiophile Grade components, thus realizing an Advanced ASIC based Discrete DAC.

Oven-Controlled Power Reference


A constant temperature power supply reference system. Everyone knows about constant temperature oscillators, but power supplies also have temperature-sensitive properties. To ensure the best quality digital-to-analog conversion, NADAC-D uses instrument-grade constant temperature reference systems.


Enhanced Clock System


Whether it is a USB Audio Clock or an AES/SPDIF Recovery Clock, the quality is exceptional. When using the USB Audio 1/F, an external 10MHz can be introduced to further improve the quality. We use two-level frequency synthesis technology, which ensures frequency accuracy and enhances jitter performance, delivering uncompromising quality.

When using AES/SPDIF, the ADD-CDR (Advanced Digital Domain Clock Data Recovery System) is used. Traditional analog CDRs cannot handle low-frequency jitter, but MF ADD-CDR can handle jitter as low as 1Hz, almost eliminating jitter within the audio frequency range, thereby ensuring the best audio quality.


Enhanced Amanero USB Audio Interface


We use a USB solution based on Amanero, which is a tried-and-tested USB audio solution in the HiFi field. We use a specially optimized version that is completely renewed from software to hardware. PCM up to 32-bit 384kHz / DSD up to Native DSD512 are easily achieved.



Optional RAVENNA network audio interface


As a heritage of the Merging Technologies original NADAC, Master Fidelity NADAC D offers an optional RAVENNA network audio connection extension slot allowing to integrate NADAC D in existing RAVENNA or AES67 networks


RAVENNA

    This open and published IP network technology had been created to meet the demands of national broadcasters and focused on essential requirements of extremely accurate clocking, high resistance to packet loss and very low latency. Initially it did not encompass high PCM sampling rates and certainly not DSD. However, it was not difficult to make changes to allow that, so Merging worked closely with the developers to make sure that sufficient channels at up to DSD256 could be handled with an accuracy that exceeded anything previously available. It remains the only logical choice for the professional and the audiophile and is now available in MF NADAC. The added bonus to using an advanced networking solution is being able to send and receive control information as well as audio data. This opened up exciting possibilities in the studio and now you can enjoy these same benefits in your own home.
