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...

“Does paying by CC really add protection? How can you prove to the CC company that you never received the goods?”

@nyev

Yes, all major credit cards offers purchase protection. Much better than PayPal. Your delivery confirmation or lack of + any correspondence with seller is a proof for your CC company. BTW, my last few sales of $10K plus were all wire transfers. Ask this seller if he will accept wire transfer.

@lalitk , I actually made use of CC protection when a car dealer ripped me off once.  They were able to apply a “chargeback” as I had the evidence.  

In the case of PayPal, the seller doesn’t charge my credit card, rather, PayPal does.  So for PayPal Friends and Family, CC companies apply the chargeback to PayPal in cases of non-delivery?  I want to be comfortable with buying the N20 using my CC through PayPal F&F, but don’t want a sense of false security.

Sorry for taking this thread temporarily off the rails!

Turns out the seller of the N20 is a longtime poster here (over 20 years), so that adds a lot of comfort!  I’ve read his posts before.  He mentions the N20 and his email address in old posts (I guess before they had filters for email addresses :)

Thinking I will proceed with the N20.

Even better!

Thanks for updating me on Steve. Hope he is doing well and will pursue his plans; I'd bet it'll really benefit the industry if he does.
