I would also really be annoyed if people with zero electrical engineering and signal processing background would pop up in forums and make claims like measurments don't matter around people that develop respected professional level audio equipment with decades of experience in the mentioned fields. These products were not developed with "listen only" audiophiles in mind until they were hijacked to this so called hobby with 90% snake oil. Otherwise they could easily place it in a big thick heavy aluminium case and stick a 5000€ price tag on it.
While what you say is perfectly sensible, losing your temper and arguing with and/or insulting your customers is perfectly insensible.
