Grimm Audio MU1 Music Player Streamer

"...this is an entirely convincing ‘transport’ solution, and is capable of sparkling results."
 
"...the MU1 still delivers one of the most musical sounds I’ve heard from digital to date."
 
Hi-Fi News, December 2020

The MU1 is the ultimate digital music source. Combined with the LS1, it forms a peerlessly elegant High-End audio system.

 
We wanted to develop the most accurate audio source we could imagine. In our experience, 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.
 
“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, which 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, 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 then 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 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, we will offer a solid alternative. 
 
The MU1 combines seamlessly with the LS1 playback system. Of course, the virtues of the MU1 can also be realized with DACs from other manufacturers. Because we love to create a stunning look for our 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.
 
The MU1 has 6 channel outputs and 3 stereo digital audio inputs.

  • Roon Core and Roon End Point integrated

Great synergy with MM Tambaqui
18 January 2024  | 

After getting my Mola Mola Makua and Tambaqui, Martin organised a loan of the Grimm MU1 for me. To be honest I wasn't sure it would make much of an improvement over my Auralic Aries G2 streamer.

Well I was in for a shock. The demo unit that Martin sent was well run in and sounder fantastic! Improved soundstage, dynamics and very enjoyable to listen to. I intended to just listen for an hour but ended up listening all afternoon and evening. I decided to order one immediately.

When the new unit was delivered I allowed it to warm up for a few hours but initially the sound was very different to the loan unit. The bass was reduced and the soundstage not as wide/deep. I ended up having to adjust the bass level on my speakers (Avantgarde DUO) to compensate. I was a bit surprised at this but, following a discussion with Martin, kept the unit playing for a few days.

I'm delighted to say that the more I used the MU1 the better it sounded. After two weeks I returned my speaker/sub settings back to their original positions as the sound had simply 'bloomed' in all aspects.

In fact, the longer this unit has been used the better it sounds.

I should also mention that you need to use an AES/EBU digital connection. Martin recommended an Accusound Silver Digital Link which is a fantastic match.
