@GearMe There’s the data from Amirs testing here but also a treasure trove of information on countless topics related to audio and a deal of well imformed members to talk about it with.
To turn data into useful information takes a deal of understanding but there’s help here for that too. ( don’t ask me though , I just work here )
Thanks!
Let me address this since we are being stereotyped as being all about measurements. If you look more broadly in this forum, you will see extensive discussions of audio science, acoustics, audio theory, etc. So we are about totality of audio science and engineering.
On the specifics of my measurements, they for the most part indicate engineering excellence or lack thereof. Where appropriate I have and continue to make comments about audibility. Many times I dismiss the visual differences as not being audible differences. No one should jump to the conclusion that the measurements indicate audible superiority by the scores seen in the graphs. For good or bad, we are really, really bad at hearing these unfamiliar distortions no matter how much we think otherwise.
In the context of this review, please take a look at frequency response error in the upgraded analog board. It shows a 1 dB drop at low frequencies. I cited research that shows that is audible and is an audible problem. That is a case of graphs matching audible differences. Schiit needs to take immediate action to investigate this problem. They need to measure their own boards, reach out to that owner, etc. to figure out what is going on.
Yes...this is helpful! Much like the info in your 'Audibility of Small Distortions' article is. Given your background/capabilities, to the degree that you could elaborate on the audibility within the context of a particular review, it would be even more helpful!
An example of this would be Tyll's use of the combined measurements and comments page at the end of each of his reviews....link below is to a recent one. Not expecting you'd want to do a full-on subjective review but possibly something like this?

His comments/interpretations can be tied back to the Headphone Measurements Explained tab where you can go to refresh your memory on interpreting/aligning measurement differences between cans
The example pages below are related to Interpreting Square Wave Responses

Re: the measured Gen 2 board dip, is it a 1 dB drop or a .5 dB drop? Want to make sure I'm reading these things right!
FWIW - on Schiit needing to take immediate action, that's on them obviously and the owner if he/she complains. I suppose if enough of their customers feel this is an issue, then that will happen.
One note though, I'm guessing that many of the Yggy owners use balanced mode and, therefore, wouldn't be experiencing this issue...just a guess.
