We actually can not (rpt not) measure soundstage height
We also do not know what the soundstage height is on the recording so there is no way to determine what the correct height is. That means we also don't know whether one component is more or less accurate when it sounds different in this area.
After doing a ton of reading and listening over about 20 years I've decided that these types of differences are most likely distortions that will improve perceived performance in one area and degrade it in another. I don't have the patience or the budget to blow through a lot of time and tens of thousands of dollars trying to find the perfect amount of various types of distortions to suit my taste. While I agree that everything can't be measured, when people start talking a lot about something as nebulous as soundstage height I tend to lose interest.
I hate to pile on but in addition to having an unbearable personality, kait is probably high end audio message boards' most recognizable charlatan. I say if for the benefit of anyone who's new to the hobby and isn't familiar with the teleportation tweak, etc.
