Sure - one can of course cheat at an informal online ABX.Thank you, Audacity!
If you see a ridiculous result on an online test, make sure to bring the person offline and take the test.
If you take Spectrum Analyzer away from him, his ears will be a fool.
The previous 16/16 result might still be valid - there's no way to know - but we should of course consider that it was the only such score out of a total of 72 (online test) attempts.
Since we have such a high number of recorded attempts by now, it should hopefully be clear that this is a difficult test for most human listeners - this should be the main takeaway IMHO. And it is difficult even though measurements indicate small frequency response differences that could be audible, plus very large differences in distortion levels of the two DACs.
In the end I just hope this casual and informal listening test helps spread the importance of blind, level-matched listening when doing subjective comparisons in audio
Note: Since you disclosed you used Audacity to analyze the stream, I won't include this latest result any future overview. Hopefully others trying something similar will be as honest.
