I attended the talk. It was mostly about knowing which FFT parameters to use and making sure you are using bit-exact path to test products. My team wrote the Windows audio stack while I was at Microsoft, and one of my professional specialities is signal processing (I managed that team at Microsoft too) so, neither was news to me. His testing and mine both use bit-exact and I have taken his measurements and replicated them on my Audio Precision analyzer showing the same problems. In almost all cases Bob's data actually matches mine. It is just that his words are far more positive and people go by that, instead of data that represents otherwise.I have shown this numerous times on ASR Forum. There is no question that Schiit DACs don't measure well no matter who measures them. Buy them for other reasons than engineering excellence.Yeh but give me credit for having more Audio Precision gear than anyone!There are no less than three of them in this picture (with one just peeking from the corner):Seriously, you are right that it is easy to make mistakes and knowledge level it takes to test mixed-signal products like DACs can be pretty large. I like to think that as an owner of such measurement gear for 20+ years, and professional experience related to everything here from analog to digital and signal processing, I know what I am doing. But if I am not, I am open to others showing otherwise. So far, that has not happened.So while there can be doubt in everything, I suggest by default you should accept the data as presented unless it is shown otherwise. Doing it in reverse means closing one's eyes to information that is purely created to make consumers more informed.
