Not quite. I explained how my measurements were made to AP folks after pointing out to Jude that he was doing it wrong. They then worked with Jude on an implementation even though I had told Jude that the right solution on APx555 requires much more research. I have explained all of this to AP folks this morning again and issues in what Jude has published.AP helped set the test up according to Jude.
In a nutshell, they have set up a test where all the distortions and aberrations of the DAC are wiped clean. And they then declare: "oh look, it is linear down to -130 db" or whatever. Well duh. Of course if you remove all the noise and distortion from a DAC, it then looks accurate. Why bother running such a test when in real usage of the DAC no such filtering exists. Talk about running off with measurements with no thought of what they really mean and what benefit and correlation there is with audibility.
On top of that Jude continues to block all of my posts on head-fi. So no way for me to convey this information there. This is not the way we converge to a consensus.
So my advice remains: please wait to draw any conclusions until I remeasure the device with my APx555. Until then, my data remains 100% valid in pointing out serious issues in the performance of Yggdrasil.
