They say this but I am running the same test and that does include +N. I am not sure how they excluded the noise when they are using the THD meter.Maybe measure only THD, not THD+N (Benchmark did that in their whitepaper)

If by that you mean planar magnetic, I have been including the HiFiman HE400i.One magnetostatic headphone should also be included in my opinion.
I hope you can figure that out. Would be nice to see a comparison of one headphone at a few different SPL. There might be some changes as headphone distortion decreases. The Benchmark whitepaper does not go very in depth here.They say this but I am running the same test and that does include +N.

Quite so, I have never heard of a plausible way of separation noise from distortion.They say this but I am running the same test and that does include +N. I am not sure how they excluded the noise when they are using the THD meter.

OK, how?Trivial with spectrum analysis. Note that Amir qualified his statement with "using the THD meter."
Correct. To do it using spectrum analysis, you would have to add up the harmonics yourself which would be hugely tedious in a sweep like this.Trivial with spectrum analysis. Note that Amir qualified his statement with "using the THD meter."
For a single number, that would be the case. But this is a frequency sweep vs THD. So if it takes you to compute one sample point one minute, then 30 sample points in the sweep would take 30 minutes.Fortunately, real world stuff that isn't horribly designed can almost always be closely approximated with 2nd and 3rd. Horrible designs might take a minute with a calculator. Literally a minute. There's probably a way to automate it with the AP that I have, but I'm insufficiently motivated.
What software do you have?At least with my software, you can display (e.g.) 2nd or 3rd or whatever harmonic vs frequency. That makes the math a lot quicker! I'm sure there's a way to add them within the AP software, but I'm lazy about learning, so I'd probably export to Excel and take 3 or 4 seconds to add the columns.
Sweetwater?There available and in stock at Sweetwater if someone is looking for one. I dont work for Sweetwater or any one else actually.
