Yeah, but these are not the measurements of the clear stock vs clear with utopia pads. Check the pdf of the utopia stock vs with elear pads, again the difference in positioning will match or surpass (in dB) the effect of the pad swap (more or less depending on the fr region). The treble region is less affected by eventual changes in seal between positions.
If we take this specific 'utopia incident' under observation, then the conclusion is more likely to be that there is a bigger difference between two stock utopias than what is measured in a pad swap. Why were those measurements pushed like that idk, but imo they are too 'contaminated' by the precursor 'incidents' of the Katz LCD4 vs Tyll Utopia, where Tyll 'discovered' the original 'utopia' review sample was 'cherry picked'.
Most importantly, my observations are exclusive to the elex, and utopia pads on a clear (the elear pads don't have the inner lining diffusor material). Of course that if the pads are wildly different, so will the sound be.
