Head-Fier since 2016. He has been known as “Otto Motor” to Head-Fiers, as “Dr. Schweinsgruber” to audiobudget.com users and Youtubers, and as “Brause” to Super Best Audio Friends and the Headphone Community. - For the purpose of confusion, he decided to pose under his real name Jürgen Kraus (“JK”) from now on. - This is a hobby. In “real” life, Jürgen is a professional geologist operating his own petroleum-exploration consulting company Franconia Geoscience Ltd. based in Calgary, Canada. He holds German and Canadian passports. Jürgen had a classical music education from childhood through high school in Germany and he has been following popular music developments since the late 1970s. His understanding of arts and crafts was influenced by Bauhaus pragmatism: “less is more” and “form follows function”.

No offense, but how did You manage to screw up the treble with Your measurement rig? A lot of people use imm6 and their treble is just fine. But Yours is a downhill, only useful to check the bass in this way
That is correct and we had this discussion before. The coupler screws the lower treble. I got the coupler from co-blogger Biodegraded, who uses exactly the same coupler and also produces identical graphs. You will have to translate my measurements to others. I have been too lazy to set up E.A.R.S.
No offense here either, but I have also seen a lot of folks using tube couplers that aren’t fine. So it is just a matter of calibration and compensation.
