Airist Audio discrete R-2R DAC, at an unbelievable $350!!!!!

I'm surprised no one has mentioned the dishonest response from the "designer" concerning the obvious copy of the Hibiki (Sosolar) design.
 

I have just spent some time perusing the massdrop communities forum
https://www.massdrop.com/buy/massdrop-x-airist-audio-r-2r-dac/talk/2098625
And I must admit the case for plagiarism / intellectual theft is pretty strong.

It is my understanding that the quality of an R2R dac is determined by having very accurately matched resistors in its ladder design. How accurately matched can one expect the resistors to be for $350.00 total cost?

A firm that selling men'a accessories,cooking,watches and so on looks very suspicious to me to buy a DAC from them looks very suspicious for me .

If it's the price you find appealing, there's also the Audio-Gd R2R DAC..."

You missed the punchline - 'Discrete R-2R".

Ah, okay, indiscreet. 🤪
