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...

Once in a blue moon a low cost product seems to rival far more expensive ones.  I had considered trying out the inexpensive Musetec DAC that many say beats much more expensive DACs, including some who say it beats the Tambaqui at a fraction of the cost.  Seems to be a lot of people who love that DAC.  The thing that made me not include the Mustec in my journey was the fact that in every instance where people claimed it beat the Tambaqui or similar more expensive DACs, the poster was feeding the DAC with a very basic and inexpensive streaming source.  My hypothesis is that the better DACs were simply better at exposing flaws of the source and therefore people concluded the cheaper DAC was best.  I’m not saying that’s what happened, it’s just a hypothesis as I said, given that I couldn’t seem to find one of these comparisons where a higher end source was used.  HiFi can be misleading like that, it’s even happed to me in this thread were I’ve attributed sonic qualities to one component only to find later that it was a different component responsible for the sonic trait.

@nyev I don’t have a problem with a lower price component sounding better but the poster claims he has not even listened to it and is making comparisons between unheard stuff.

My friend, on the internet anyone can say anything. But you are dead wrong about what Musetec users are feeding it with. Take the one example you cite, that of a comparison with the Tambaqui. That comparison was made here on the Musetec thread. The writer is a principal of Network Acoustics manufacturing sophisticated ethernet filters. The DAC he chooses is used for testing as well as pleasure. He has tested every variety of front end on his DACs.

I know that with 1475 posts it’s hard to figure out what streaming sources are being used by each poster, but if you ask, I’m sure they’ll let you know. There are some very high end sources being used because the DAC is worthy of them.

The DAC is considered cheap by some standards. But look at it very closely; it is not cheaply made.

In the interest of transparency, the guy who compared the Musetec with Tambaqui became a distributor for Musetec right around the time he shared his thoughts on these two dacs. Of course this doesn't necessarily mean his comparison is biased, but it is an important data point that must be taken into account when citing the example.

As for the comparison between Grimm and Gustard R26, I'm currently comparing the R26 to Pontus II at this very moment. Is the R26 streamer function as good as Grimm? Based on what I'm hearing, no ... not even close. I think the R26 streamer (not the DAC) plays at the level of Node 2i or many other sub $700 streamers in the market, but it will not outperform higher end streamers. My take on the R26 is that the value it provides is in the DAC section, which is actually very very good. But the streamer functionality is more of a convenience feature and not a serious attempt to become a giant killer. Compared to Innuos Zenith MK3 (which I recently sold) and Aavik S-280 (currently in my main system), the audible difference between R26 and these two are readily apparent.

In the interest of completeness, "the guy" wrote of the comparison months before over at head-fi, well before he became a "distributor" for which he has never done advertising.  Also, the pittance one can make being a distributor for Musetec in the UK is not going to affect the opinion of one who has a reputation to uphold for his primary business that focuses on the integrity of the incoming digital audio stream, at least IMO.
