It's just to have room for higher SPL and don't have to put too much pre amplification before EQ to avoid the need of amplifier.

K612 fan ! Nice to meet you ! :-D

BTW thank you to have taken the time to explain me that what I said was looking like manipulation. I take note

I personally didn't take the time to read the text because it didn't look like a scientifical document. No explicite methodology part and so on. The only thing that can't be subject to personal opinion are graphs. About the figure 17, it's not the K371, it's another headphone on the graph.

I had no intentions to support a position. Do you know what cognitive biases are ? I hope yes because I know what they are. I'm not the kind of people that want to manipulate others.

It's to not wast your time

It's to not lose their time

I wait Crinacle BK 5128 measurements. I also wait AutoEQ researchs to see how Crinacle's 5128 behave.

I totaly agree ! ;-)

Sometime the Oratory is above BK and the opposite happen. It's rather confusing. That's why I doubt.

I agree

Look at the graph only

Do not read the text, it can be biased

Edit : Don't wast your time reading it

Do not read the text and read the graphs

I think because of this : https://daystarvisions.com/Music/HE4-Headphone_Frequency_Response_Graphs.pdf

He has some cognitive dissonance, I think. You can't say that a bassy headphone is as good as a bass rolled off one. That's totally illogical.

I could be the K612 Pro because I'm rather good but I need big power to drive my brain. XD
