 Consider earpad aging as a factor here--I suspect that's where most of the difference is coming from.  Here are those measurements (click on the images to see a larger size):   Here is our system that I used for the measurements above: G.R.A.S. 45BB-12 KEMAR with anthropometric pinnae for low-noise earphone and headphone testing This is a next-generation headphone testing system, and you can read more about it by clicking here: Next Generation Headphone Testing Audio...

 That's Dan. (That's a cool video, by the way, so thanks for linking it.) He's done a lot of work in the industry--respected, seasoned, experienced, and I'm glad to see him working on his own IEMs with Periodic Audio.
The plots I posted (as @FUYU pointed out, and as was stated in my previous post) used DF compensation. (Smoothing was 1/12.) Here is Periodic Audio's measurement of their Be model (which I've posted as the first graph below, cut off at 20kHz)--this is raw and not smoothed. (Click on the graphs below to view them in a larger size.) Dan describes his measurement setup at the following link: In mensura et in arte musica aurem Here are my raw plots, no smoothing, with a slight...
Make sure not to miss the headphone measurement seminar "Introduction To Headphone Test" with Chris Gill of Audio Precision.     The first one is on Saturday, April 8, from 2:00 p.m. - 3:00 p.m., and then again on Sunday, April 9, from 11:00 a.m. to 12:00 p.m.   Both sessions are located in the Atrium II Demo Suite at CanJam SoCal 2017.
My iPhone 7 Plus (with Apple CCK) works with the Chord Hugo 2. I'm listening to it right now.   As for iOS version, I'm on v10.3.1.   I'm not sure how old my CCK is.
 My favorite of the three is definitely the Periodic Audio Be (beryllium). I'm listening to it right now from the Chord Hugo 2 (pre-production unit), and it's an extremely impressive IEM for $299. During the CanJam SoCal video shoot, I didn't have time to listen to it for an extended period, but I'll keep it in my backpack to give it more listening time. First impressions: I'd call the Periodic Audio Be's signature neutral-ish as I'd personally define it (as "neutral" is...
 Rob sent me one of his Audio Precision APx project files (as we both use the same model Audio Precision audio analyzer) and I incorrectly assumed the last noise floor modulation measurement in that file was the one shown in this thread from his Singapore presentation. I just double-checked, and it turned out I was wrong. Rob sent me an earlier project file than the one he cites in his presentation in this thread--it's dated about one month earlier than the plots in his...
NOTE:  If you can't see the embedded video above, please CLICK HERE to see the video.     There are several new products being launched at CanJam SoCal this year, and we unveil them for the first time in this episode of Head-Fi TV.
