I hate to say this, but Grimm was totally absent in CAF. I looked for it. Zero. I think the fad is dying up pretty quick. I love to be proven wrong. All the OG Grimm enthusiasts I know gave up on it. Admittedly my sample size is small
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...

I just looked up the Grimm MU1. Retail price $12,500 without any internal SSD included. Wow! Pricey. A couple of observations: 1) Processor: Intel i3 2-Core. Definitely sufficient for Roon with no DSP, and with not a huge Roon library. But certainly not very powerful for those who use DSP (not me) and with big libraries 2) Memory: 4MB RAM. Again, not impressive. 3) No USB audio (to DAC) output. Hmmmm…. I am definitely curious about Grimm, given the reports & reviews, but these observations give me pause. A friend of mine ordered one a few days ago, so I should be able to learn more from “real life” experiences in a few weeks. |
Thanks. I am reading this thread from the start now

@nyev : of course, we all make purchase decisions based on what matters to us. I fully understand that. I will be curious to learn about your experience once you get it, especially as it pertains to comparing with your Innuos ZENith MK3. I have to say though, you change & swap things around so often, in a very short period of time (by my standards). I would personally have a hard time fully grasping how something sounds for such a short period of time, especially when so many other components in the chain are also being swapped at the same time 🤷♂️
How do you plan to connect the Grimm MU1 to your Tambaqui? |
@ghasley : thanks. Sorry, I don’t remember, do you have a Grimm MU1? |
The reason I was asking is the Mola Mola Tambaqui has a network bridge built in. Meaning you can “connect via Ethernet, RJ45 cable” so to speak, to your upcoming Grimm MU1 too. It will be easy to compare & contrast one vs. the other.
The Phoenix USB did not do much for me when paired to the Zenith MK3. Sound changed a bit, but I was not sure if for better or worse. As you said, it must depend on the DAC, and ‘or we all hear differently.

That’s because you did not restore from back up initially when setting up your Grimm as the new Roon Core:
However, you can still restore from existing backups (of the database). Go to Settings (on Roon), then Backups, then pick at the bottom Find Backups/ Browse. I hope this helps |
@fastfreight : if your Roon database is in your network, then I think you will need to do "add network share" in your Grimm before you can access your files. I am sorry I cannot help much not being there. You can also try to copy the Roon database from USB hard drive to the internal storage of your Grimm, but I really don't know whether this is possible. |
Right there…. I would personally NOT want to replace a piece of gear with those two attributes with an alternative that yields a lesser result. Less full, and less natural depth. But that’s just me.
On another note, my friend who was getting the Grimm MU1 is going silent. I don’t want to bother him with questions. Give him the proper time to evaluate

@lalitk : happy holidays my friend |
@nyev :
They all say the same. Completely understandable. They are there to sell you their stuff. Not cables. Make it all one-stop solution, with no need to buy anything else. Solid marketing strategy. As you eloquently put it by the following, which is spot on:
Also:
Yup! Same thing. One-stop solution, no need to buy anything else other than $10K for Grimm you are about to shell out. Marketing department working “very hard”. 🤯🤦♂️

This is getting very confusing 🤷♂️ The very reason Amir M and Cin Dyment win it every single time
What do you mean? Muon from Network Acoustics comes with the Network Acoustics own Ethernet cable

@nyev : thanks for explaining. I am sorry I misunderstood you. I follow this thread with great interest. Thanks for sharing |
@fastfreight : every single YG speakers owner I know, personally or virtually online, also has Kubala Sosna cables. What a coincidence! Or is it a coincidence? I have no idea. |
