Which DACs are known to be sweet/rich/relaxed?

Thanks again @verdantaudio Where does the Grimm MU1 fit in?

Grimm MU1 reviewed as:
Neutral, clean, fast, transparent, resolving with high resolution. More convincing than K50 with more precise imaging.

K50 reviewed as:
Full, smooth, liquid, lush and relaxed.

Same reviewer deemed the Pink Faun 2.16x drier, tighter, more accurate and more clinical than the K50. He preferred MU1

MU1 is supposed to have good synergy with my Mola Mola Tambaqui DAC (Bruno Putzeys designed the Tambaqui and co-founded Grimm).

All should be seen in the context of my soon-to-arrive Boulder 3010 and 3060, with Focal Stella Utopia EVO speakers.

I have not heard the Grimm and have no POV.  I would bet the Oladra is a better compare.  It is definitely better than the K50 on a technical basis.  

Not sure how you feed the DAC, but the Innuos Phoenix USB has transformed my system. It creates a wonderful warm analogue sound

Robert1976 - are you replacing the Essence electronics with Boulder? Only that’s where I’d say your issue lies. I’m going through same situation with Essence right now. Did you ever try Tambaqui direct to amp? Sound is considerably more relaxed but lacks the dynamics rendered by the pre. In my room, I’m considering doing what I did with an earlier Naim 252/250 combination which suffered the same issue - replacing the pre with a tube pre. This gave a beautiful result. Tambaqui is not a ’bright’ dac. It’s incredible resolution, though, accentuates the inherent nature of a system’s sound signature. Essence is uber neutral and high energy. Focal tweeters can be ’bright’, too. I had to replace Sopra 2’s in the old Naim system because they made my ears bleed.

Reimyo 777 or 999.  These dac's are relaxed and "tube" like or sound similar to Audio Note DACs.  They only do cd redbook but holy smokes they sound holographic and warm and like music

Love this stuff
