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...

+1, @lordmelton 

If you have the capability to add external clock, you must try this option. It’s what I call the ‘X’ factor. Based on what’ve experienced with my DAC and N20, a high quality 10MHz external clock is a next level upgrade.

No affiliation but there is a preowned Grimm just listed for sale on that other site. 8tb ssd, 8 gig ram. For those in Southern California, you could pick it up.

 

Once again, there are alot of opinions and everyone is certain of their path. The OP seemed to be interested in a one box solution and seemed to be interested at pricepoints between $10k and $20k. The Aurender is hard to go wrong with…and I wouldn’t worry too much about Antipodes QC…its great gear. The Innuos is also terrific and their customer support is exceptional. One thing the Innuos has going for it is you can use Roon…or not. The Grimm is optimized for Roon but if Roon isnt your preference then scratch it off the list. 

 

Alot of posters enjoy their dsd and for good reason…its the cleanest dirty shirt in the digital hamper. Just like in vinyl, there are millions of variables (phono stages, tube vs ss, step up transformers, cartridge choices, TT choices, idlers vs belt drive, multi motors, mass vs lightweight, cables, wires, isolation, power cables and treatment). I listen for enjoyment, I prefer the least number of variables to troubleshoot…but I recognize that others in our hobby prefer otherwise. There are more than a few setup photos on the Audiogon systems section where you can almost imagine the marital status of the individual and there interior design preferences. Ive mentioned before in other posts in other threads that there is a very valid (for them) subsection of individuals in our hobby whose setups more closely resemble something out of a Rube Goldberg drawing with special cable lifters, rare African wood footers and almost always….a single chair (usually a barcolounger with soiled/worn velour fabric with some Taco Bell stains here and there). Its all good, everyone gets out of the hooby what they want.

 

I assume though that the OP is after a clean install by his excellent choice of the Gryphon Diablo and their inboard dac. He can choose a well built/engineered server/streamer and elevate his enjoyment. One box, one power cable, one cable to his Diablo and accomplish his goal. OR…he can construct a shrine to “I can make it work but it takes 6 boxes, 6 power cables, numerous connection points and other unecessary tweaks and variables with no guarantee it will sound better because in most cases they havent experienced a five figure server/streamer in a proper way. For many here, they have an abundance of time and they enjoy the trial and error of introducing complexity. That doesn’t describe me.

 

Demo it in your room with your gear. Decide for yourself, there is no best and there are many roads to get where you want to go. 

Just to add to this thread. I have owned the Grimm for a fair amount of time! 3+ years. One of the earlier adopters.

Having met and spoken with the manufacturers close to nearly a decade back gave me the strength that they know this domain as well as others, and implement theory into practical to see if it actually works and sounds better.

Being able to play in mostly all formats for today, digital and analog the MU-1 has given me great enjoyment with some of the longest listening session which I have never done before, due to it’s convenience.

There may be other flavours, but do try it out and then decide.

One thing for sure, you won’t go disappointed that I wish I had heard this other component as its ’so much’ better than the MU-1.

You’ll only be playing in the space of personal preferences off one component over another.

A quick off topic aside. The A.N.Jinro-Orangutan 96 pairing must sound utterly natural and involving
