Master Fidelity, originally founded in 2015 as Merging Fidelity, has been actively participating in the development of the first NADAC range under the Swiss brand Merging Technologies.

Since 2022, after Merging Technologies was acquired by the German group Sennheiser and discontinued the NADAC range, Master Fidelity has taken over the NADAC brand and based on its solid expertise, specially in chip design and clocking, developed a completely new range, the MF NADAC range, bringing audio quality to new heights.
