MU1

The MU1 is the ultimate digital output music source. Combined with an LS1 it forms an extremely elegant High End audio system that hasn’t seen his peer.

We had the desire to develop the most accurate audio source of our imagination. In our experience the human hearing system shows an incredible sensitivity to anomalies. Even unimaginably small abberations appear to be audible. In principle digital audio does offer perfect reproduction. Its sonic quality however is limited by the implementation accuracy of the physical and mathematical laws that affect the conversion from one format to another. Grimm Audio strives to bring you confidence that all technical details are taken care of to the greatest extend. As a result the reproduction system steps out of the way of the music.

“The MU1 is the ultimate digital music source: attractive, reliable and precise”

With the MU1 our goal was to set a new benchmark in music player design. The Linux based computer system brings solid data integrity. Our in-house designed FPGA interface board, that forms the heart of the MU1, offers breakthrough performance levels in format conversion and receives automatic updates whenever we have pushed the boundaries again. Needless to say that the MU1 features our trademark ultra low jitter clock. This is a music player worthy of the name Grimm Audio.

Once excellent sound quality is ensured, the quality of a music player is defined by the user experience. For this we partnered with Roon Labs, who in our opinion are in the lead when it comes to a rich and engaging music experience that appeals to your whole family. The MU1 runs Roon Core server, so no extra installs are necessary. Just pick up your tablet and experience the music. For customers who prefer to only run a simple playback system without Roon’s extras, we offer a solid alternative. 

The MU1 combines seemlessly with an LS1 playback system. Of course the virtues of the MU1 can also be deployed eminently with DACs from other manufacturers. Because we love to create stunning looks for our equipment, the boundless versatility of the system is wrapped in a cabinet of minimalistic elegance, so a MU1 will easily become the gem of your living room.

The MU1 has 6 channel outputs and 3 stereo digital audio inputs
