For us, it was one of the highlights of the High End Munich 2023: the introduction of the Grimm MU2. So we couldn’t wait until we had one in our hands to check it out. Does it disappoint after all the “high hopes”? Well … you already know that answer. But that doesn’t take away from the fact that we’d like to take a closer look at this beautiful device.
A few years back, Grimm introduced the MU1. That was a pretty “disruptive” device. It’s a streamer with a Roon core (or server) and as icing on the cake: far-reaching upsampling of the digital signal. That will give better results with all dacs, connected to it. Due to its excellent sound characteristics, the Grimm MU1 ended up in many a reference system. And rightly so.
The Grimm MU2 is not the successor to the MU1. It is a complementary product for those who do not want to work with a separate d/a converter. The Grimm MU2 is a streamer with the same Roon core as in the MU1 and now also a built-in d/a converter. A very special converter, about which more later.
But it doesn’t stop here. In fact, the MU2 also has an analog preamplifier with analog volume control. And it has a headphone amplifier. This signal path is also completely analog: no analog-to-digital conversion or other DSP-like conversions: it simply involves a relay which keeps the signal path as short as possible.
Then the price for all this beauty: 18000 Euro. Yes: a lot of money. We will agree on that. But realize that you are not only buying a streamer, but also a Roon core (unfortunately the license is not included; we would have liked that), top-of-the bill d/a converter, a headphone amplifier AND a wonderful analog preamp. All in all, the MU2 is a very interesting package deal!
