Just wondering if you were following the conversation and who I was referring to. Please see above. Sorry no crusades (bad knees) and no monking around either as I have not taken a vow of science, typo I meant silence.

They probably measure better than most of the Schiit R2R offerings.
Welcome to the forum! Any suggestion and links for a cheap one?For fun, it would be interesting to see measurements of vintage R2R from the 90-s. I think the DACs built around PCM63 or UltraAnalog chips represent the pinnacle of technology of that era. They sound surprisingly good even today, fwiw, when fed clean signal. They are oversampling designs so should not suffer much from the HF droop. Can be had relatively cheaply these days from the familiar used gear outlets.

Thanks. I do plan to test my own Mark Levinson DAC with PCM1704s in there: https://audiosciencereview.com/forum/index.php?threads/amirs-todo-thread.2074/page-8#post-66373
Would you suggest electromechanical relays do the bit switching as well. That sounds tweaky and stuff.I think we should promote the binary weighted resistor DAC as the next big thing in audio. It has very desirable audiophile features like difficulty of design and manufacture, instability with temperature, glitches, etc. all to an even greater extent than the R-2R DAC. It could just add that audio magic that people are craving.

Perhaps you can get hold of a recent Metrum Acoustics DAC, they use custom-designed R2R ladder chips and claim close to 24-bit real world resolution in the latest iteration. They are NOS designs, so may not produce the cleanest spectrum, but the linearity tests would be interesting.

That graph only shows linearity to a bit more than 120 dB/20 bits though. But sure, if I can one for free to test, I will.Perhaps you can get hold of a recent Metrum Acoustics DAC, they use custom-designed R2R ladder chips and claim close to 24-bit real world resolution in the latest iteration.
