Grimm MU1 Streamer - Really "The Best"?

@thyname , no worries. Will continue sharing; in return I receive great advice or inspiration, as with the recent case of the Muon Pro kit. I will wait a few weeks to go down that road as I am still getting to know the MU1 with the Tambaqui. This setup takes a lot more work as I mentioned with speaker positioning. Just when I think I have it as dialed in as it can be, I mark the floor and make the smallest adjustment, and sometimes it gets worse but I’m still finding some adjustments are still improving things. Managed to improve the focus yet again just a few hours ago by toeing in even more and bringing the speaker’s forward a few millimetres. Can’t recommend Herbie’s Audio Spike Decoupling Sliders enough. They provide an unreasonable boost in scale and separation AND they make speaker adjustments a cinch if you have hard floors. And these adjustments are tiny…. But yeah I have enough to deal with currently but the Muon, and fuses will be the next step after cables.

Thankfully I’ve managed to add these pieces without too much expense - the MU1 just prior to the significant price increase, and the Tambaqui I was able to purchase used for what I think was quite a good price.  And if it all works out (I think it will) I’ll get to eventually sell my three Innuos devices and a power cable and two USB cables.  Would actually like to keep both of the Phoenix devices in case I ever have a use for them, but can’t justify that.

Little late to the party but received a Grimm MU1 a couple days ago to demo. Quite honestly, I’m shocked by the transformation this unit makes to my system. System had NUC for Roon, then my Lumin T2 as my streamer into my Nagra tube dac. The Grimm eliminates the NUC and the Lumin and now I go straight into the Nagra with the Grimm. Using an AES connection.  
 

Pro’s:

1. much wider soundstage and more “musical”
2. wow factor improvement on bass especially at lower volumes
3. midrange and vocals much clearer
4. Hard to turn off my system. Listened for about 6 hours yesterday

Con’s:

      1.  A little slower than NUC getting to songs

      2.  Will probably end up spending more $ on audio….again

Hi all,  my mu1 is settling in so sweetly with my Tambaqui.  I also have the  Muon Pro System from Network Acoustics.   I have previously taken the Muon in and out of my system and always preferred it.  As @lalitk says, the cables are nice.  The ‘system’ includes their network cable before the filter;  the cable exiting the filter has a fixed attachment.   So I tried the mu1 Tambaqui combo with and without the Muon Pro.  It is better with it.  It is less noticeable than prior to the mu1, but still a noticeable improvement.  And YES @nyev the fact that it is non powered (passive) is very appealing. And my addition of the mu1 eliminates my Nucleus + as the Grimm runs my Roon core. (And eliminates my HDPLEX LPS powering my Nucleus).

+1 on @lalitk ’s suggestion of passive filter. I have the ENO filter which is one step below the Muon and still very happy with the results. It helped remove any lingering digital artifacts in the chain.

@nyev

I very much doubt that you would feel the need to keep Phoenix pieces around once you hear Muon Pro Kit. I kinda miss the simplistic (passive) approach and the positive attributes of both Muon and ENO filters. In my case, Muon Pro arrived little too late on the scene otherwise I would have gone for Muon Pro Kit in a heartbeat. I am now deeply vested in another solution to look elsewhere :-)
