Well now... 400$ Mark Levinson amp new...

i can't address this particular clone, but from my experience with high-end headphones you should not underestimate the resourcefulness and genius of these chifi manufacturers--i've heard dirt-cheap knockoffs of expensive sennheiser, shure, etc. which are just as good as, and in some cases, better than the real thing.

Hey, the ML clone only measures 12" x 6" x 13"!  

So it is a ML mini me!

That’s good. Amps are too big and heavy... its 2018!

I cannot recall who and when, but someone here on the Gon said in an earler thread that he had bought, and was using, the Chinese DarTZeel amp, and it was the best he had ever had.
