What about all those Chinese DACs?

Ditto Audio-GD.   Utilizing I2S input their top R2R DAC relegated an Esoteric K-01X to my bedroom system.

I have Topping D90 III SABRE.  It is simply outstanding. Dynamics, detail soundstage and imaging, all top notch.  One of my best purchases.   Could come off as overly bright in some systems and to some ears. “Valve” sound mode helps.   Synergy and personal preference matters.  No doubt however that it is a top notch performer.  Has helped take my Ohm Walsh speakers up to a higher level with simply breathtaking results. Very happy camper here!

I have two Musetec DACS the MH005 and MH006. They are both fantastic and unfortunately got hidden in the Holo May's shadow. 

They are more than capable of upping their performance to whatever system changes you implement. I've heard many, many high end DACS but for me I'm more than happy with this underrated brand.

+1 specs are nearly irrelevant in determining the sound quality of components
 

Gotta disagree 100% on that one.  Specs and measurements are the ONLY way to determine ACTUAL sound quality.  Ignoring that fact can be a slippery slope.
