AKG Perception P220 to Neumann u87 5 min mod ( p200, p100, p400, p420? )

Hi @s wave ,

This circle in which we float, called Groupdiy, operates with technical terms, with clearly defined parameters, we make measurements, our approach is scientific, objective.
Otherwise, we end up contradicting each other permanently for subjective reasons, for beliefs, individual psychoacoustic perceptions, personal preferences, very different aesthetic, artistic, cultural orientations.

Edit:
Let's not pollute this thread with @kingkorg 's excellent mod with off topic discussion.

I don't think it is off topic ~ when discussing the high end frequency of a specific mod vs it's targeted model. (I think your posted definition uses very subjective words btw) I wanted to hear, from those who have made mods, and how they compare the high ends; in terms of that classic 'Neumann air'. Does a dual diaphragm inherently have a tidbit of smear/phase shift vs a single?

Does a dual diaphragm inherently have a tidbit of smear/phase shift vs a single?

That's a really good question, and since it's not specific to a particular microphone brand or model, I think it deserves a separate thread. At least in the case of capsules with a central screw, I am convinced that a capsule with a double diaphragm has a different spectral and polar behavior compared to a simple capsule. I think that in the case of a dual capsule, the central screw influences the amplitude and the way the rear diaphragm vibrates, resonates, damps, rejects, etc.
It is possible that @kingkorg studied this aspect, and knowing that he is very pedantic and objective, he may have made measurements.
On the other hand, phase shifts are ubiquitous in acoustic reality.
