And you have just demonstrated the blindspot by defending science with that statement. Because audio equipment contributes to an aesthetic experience, useful research would typically need to be comprised of both quantitative and qualitative, where the qualitative would take that into account. And to design qualitative research methods and do the resulting analysis of the data, one would have to understand theories from social science and the humanities, which a lot of researchers in the hard science would not have a clue about, and thus why they feel it can be "deliberately eliminated." To rely only on the quantitative is sort of like thinking one can analyze cake and compare it to pie by analyzing it's chemical composition and other physical characteristics without doing research into what makes it taste good and having people taste it.
But I guess it depends on whether your end goal for research is how the equipment measures or which people will like better
