Grimm MU2 Music streamer and DAC
Reviews
"I've recently become interested in the Grimm MU1. While reviews of top end players from Innuos, Aurender and Antipodes and others are typically all very positive, the tone of the many pro reviews of the Grimm go far, far beyond, with some reviews resorting to using superlatives and gushing of positive system transformation and not being able to stop listening to material, etc.. HiFi Advice and Steve Huff (actually calls it "magic")"
"The best I have heard"
“The Grimm was reaching the parts many other streamers had failed to reach.”
"Grimm gets Stereophile Recommended Component award"
From the manufacturer
We are convinced that smart integration of functions yields higher audio quality. The MU2 combines a music streamer with a superb DAC and a reference quality analog pre amp. Its built-in DAC takes full advantage of the Grimm Audio low jitter clock and high performance FPGA processor. A relay based analog volume control enables the MU2 to become the true ‘hub’ of your hifi system for both digital and analog sources. Just like with its sister product, the ‘digital output’ MU1, a Roon Labs Core server is on board so no external computer is needed to enjoy perfect streaming.
“The MU2 offers full integration of functions, from Roon to analog volume control, with revolutionary sound quality.”
At the heart of the MU2, Grimm Audio’s proprietary Major DAC can be found. It is of a groundbreaking discrete design that makes optimal use of our own FPGA board. In a unique way our high resolution Pure Nyquist upsampling filters are combined with a fundamentally flawless 11th order noise shaper of 1.5 bit.

As a result the MU2 reproduces micro-details so well that it allows a deep emotional connection to the musical performance. The stereo image is of groundbreaking quality. Its serenity invites prolonged listening sessions.
If you love your loudspeakers and power amplifiers but long for a fundamental update in sound quality and streamer experience, the MU2 is designed for you.

Reviews
Jaap Veenstra and Martijn ten Napel of Dutch online magazine Alpha Audio made video reviews of the show (in English) and visited our room twice. It’s clear that they were blown away. You can find their response to the MU2 sound in their first day report (at 7’24”) and especially in their third day report (at 16’15”), after they returned. Jaap also did a video interview about the MU2 with Eelco Grimm.
" it was in listening to the familiar that highlighted the Grimm MU2’s exceptional performance as I heard more deeply and more fully into the sounds of familiar music than I’ve ever experienced in Barn. And the degree to which the Grimm’s ultra-clarity, dimensional wholeness, and superlative resolution had me cursing in delight and shaking my head in wonder at the new sounds from familiar music even after more than a month of listening"
"the Grimm MU2 pulled out the richest and most fully resolved sounds of music I’ve had the pleasure to live with"
"If you want to hear the best digital music reproduction I’ve heard by an obvious and distinct margin, you’ll need to find a Grimm MU2 to listen through"
