MU1

“In conclusion we can only call the Grimm Audio Mu1 a statement effort in digital Audio”

Henk & Marja, 6moons

The human hearing system shows an incredible sensitivity to anomalies. Even unimaginably small aberrations 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 extent so that the reproduction system steps out of the way of the music.

With the MU1, their goal was to set a new benchmark in music player design. The Linux-based computer system brings solid data integrity. Their in-house-designed FPGA interface board, which forms the heart of the MU1, offers breakthrough performance levels in format conversion and receives automatic updates whenever they push the boundaries again. Needless to say, the MU1 features their trademark ultra-low jitter clock.

Once excellent sound quality is ensured, the quality of a music player is then defined by the user experience. For this, Grimm partnered with Roon who in their opinion lead when it comes to a rich and engaging music experience that appeals to the whole family. The MU1 runs the 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, Grimm will be offering offer a solid alternative. 

The MU1 pairs seamlessly with the Dutch and Dutch 8c loudspeakers and from Kii Audio, the Kii Three & BXT systems as well as Grimm’s own LS1. If you prefer not to partner with an active system the virtues of the MU1 can also be realised with DACs from other manufacturers. Because Grimm love to create a stunning look for their equipment, the boundlessly versatile system is housed in a cabinet of minimalistic elegance, so the MU1 will easily become the gem of your living room.
