Good measuring DACs vs.

I find the Stereophile review of DAC 3 HGC, to put it gently, weird. The reviewer was comparing it to PS Audio DSD by having PS Audio DSD connected to the Benchmark analog in, and stated he heard no difference between the two DACs. Well no 💩!!!

I owned two Benchmark DACs, the DAC 1 years ago, and DAC 3 HGC fairly recently. I will say the DAC 3 HGC is slightly more musically engaging than the original DAC 1, but that’s not saying much. I sold it because it sounded like a studio monitoring tool, cool and dry, unable to convey emotion. 
I haven’t heard the Tambaqui, but would love to. So I can’t speak to it but will take your word for it.

Perfect measurements don’t translate to good sound. I stumbled upon an ASR review of the Marantz SA-10 SACD player on YouTube and watched it just for 💩s and giggles. The ASR crowd in the comments was hailing Amir for saving them $7400 because the $99 Chinese Toping DAC (his reference) measured much better. Well guess which unit sounds better and not just marginally…

PS.  I'm not talking down either of the DACs you mentioned.  I'm just saying measuremets aren't what makes them good.

A lot of people like the sound of the Tambaqui and to clarify, I found it to be a more enjoyable sounding DAC than the Benchmark but neither provided the level of enjoyment for me in my system that my Mystique EVO Pro provides. Even the SMc DAC-2 is more musical. It is hard to verbalize since the Tambaqui basically had no audible flaws and had I not had other DACs here I probably could have been happy with it. Even the Benchmark is respectable for what it does, which is clear, clean, absolutely distortion-free sound, but for whatever reason, I am not hearing the level of emotion that I need in my reproduced music. Regardless of whatever flaws they may have, the EVO Pro and SMc DAC-2 both display a strong level of emotion in the music, IMO of course.

m0ns List at sonusapparatus, under DACs, provides a description that is in alignment with what I hear from the Mojo Audio Mystique EVO Pro.

"A very fun, organic, and rich sort of DAC with both fantastic micro and macro ability, great impact and slam, great control and grip, and organic presentation with a bit thicker weighting, and pretty great stage too, more forward in things, although sometimes strangely picky. Does what it does really well, super fun and engaging without being offputting, limits of coloration for me."

Advertising dollars tend to make things sound better than they actually are. 😁

Specs or test measurements don't equal musicality.  They are not human ears!
