Mutec REF10 The Audiophile 10 MHz Reference Master Clock



The MUTEC REF 10 is an audiophile reference master clock generating 10 MHz signals with industry-leading low phase noise (i.e. jitter) to significantly improve digital playback systems. As the conductor of your digital audio orchestra at home, the REF10 will inspire you with unheard-of clarity, graceful dynamics, and pure music. It is the most flexible, most compatible 10 MHz clock on the market allowing you to spend less time worrying about integration and leaving you with more hours to enjoy blissful playback. Currently available digital converters, master clocks, and audio re-clockers perform acceptably when reproducing or processing digital audio. Even so, we at MUTEC felt that the existing solutions fall short of delivering the full potential of audio productions. In our commitment to advancing the state of the art and science we set out to investigate the possibilities to further enhance the performance of digital audio systems. The result of our extensive research is the REF 10, our first Empyreal Class product combining uncompromising engineering with the beauty of simplicity and the utmost clock precision.
