Grimm MU1 Streamer - Really "The Best"?
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 MU1 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") have such reviews.
Given the delay in availability of the Innuos Pulsar which I'm told will be better than my current Zenith Mk3 + PhoenixUSB reclocker, I am interested in replacing my streaming setup with a one-box solution that includes a high-precision clock. The new streamer will continue to feed my Gryphon Diablo 300's DAC module, which I have no interest in replacing.
I'm actually a fan of Innuos, after they improved the sound of my Zenith with firmware updates and after I added their PhoenixUSB reclocker. I appreciate this commitment to improving sound quality which is why I was so interested in the Pulsar.
The trigger for considering an upgrade is not for improved sound, but rather, to solve some issues I have with too many Audioquest power cords coiled and clumped together. I will get to lose one of them and one of my USB cords with a one-box streamer. I've noticed my sound is very sensitive to positioning of my AC cords and find I often need to re-adjust the PC feeding my amp to get proper sounding vocals at center stage. One of my subs also seems to be picking up AC noise when the crossover is set above 60Hz. The second trigger is simply system simplification, removing one box. All that said I don't really have any complaints regarding sound, and the PhoenixUSB reclocker truly did improve the sound of my Zenith.
While the Grimm MU1 has it's 4X upsampling up it's sleeve with reviewers absolutely glowing over this feature and it's extreme ability to separate tones to the left, right, front, and back far better than the rest, I don't see that Grimm has gone to any lengths with regard to power supply management in the way other brands do including Innuos. The MU1's ultra-simplistic interior doesn't bug me, but the lack of transformers and power management makes me wonder....
Are there any updates from folks who have directly compared the MU1 vs similarly classed streamers from the competition? Did you find it to be as revelatory as the pro reviewers found it? And, how does it compare to other streamers with it's 4X upsampling disabled? Does it sound like it suffers from it's lack of power management? I do see that the clock should be very good...
Hi Carlsbad2, now that the MU-1 has a few more hours of use, do you have any follow-on comments or preferences. I have the Dave, M-Scaller and Zenith MkIII and even though I prefer user experience with Roon, I prefer the SQ of the Innuos native player. A move to the MU-1 interests me as others have preference the MU-1 with Roon over the Zenith with the native player. Given you were using the Chord Dave, I wonder if that was your conclusion or if you ended-up on a different route. Thanks, Neil |
I agree in my limited tests: Mac mini running Roon vs Euphony Stylus and Euphony sounded better; Innuos Zenith MkIII Sense native player vs Roon and preferred the Sense player over Roon. My conclusion / assumption is these designers maximized (or maybe "tuned / shaped") their native players to get best sound versus doing a pass through of the Roon player. Several people mention their preference for the MU1 running Roon over Innuos (I'm assuming running the Sense native player), and I'm guessing either Grimm has figured out how to get better SQ out of Roon, or Grimm maybe is running or shaping the SQ....

Hi @nyev - Sorry if this was stated previously, but I am wondering if you were comparing the MU1 (running Roon) to the Innuous Zenith’s native player or Zenith running Roon? Reason for asking is I find the running Roon (core or end point) to be a bit smeared and narrow sound stage on my Zenith Mk3, and the Zenith native player to be more 3D, wider, deeper and a tad bit of mid range dip with vocals enhanced and out front, which I think you noted in one of your posts, so I assumed you were comparing the MU1 with Roon to the Zenith with native player. And given your conclusion that the MU1 was the keeper has prompted my interest in testing the MU1 too, as I like Roon for additional music information presented and clicking through for music discovery and would rather be using Roon as my primary player. Thanks, Neil |
