MU2

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. If you like to read more about this technology, please check out the Major DAC blog.

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.

The MU2 has 2 stereo analog inputs and 3 stereo digital inputs. It has outputs on XLR and RCA, and headphones jack.
