There's no document that people can refer to. There's a lot of mythbusting needing to be done on memes like Stax needs a few days to fully charge the diaphragm and so on. There's also a lack of information and testing around the amplifiers. I've never been given a straight answer as to why the 007 allegedly needs more current than other models (greater diaphragm area?).
As for HF, well, I once told astrostar at one point that he would be first to swing on the day of the rope and the mod just deleted the death threat and gave me a civility PM. That's the standard they set, deleting every barrier to a headphone sale.
