The conversation regarding the utility of objective measurements and audio quality continues . . . with the seductive siren call of quantitative "certainty" gaining more traction. Certainly the research by Harman International's Sean Olive is a huge step forward, and is worth a look if you are interested in the topic or are thinking of trying to upgrade your headphones.
What is most interesting, at least to me, is how well measurements can reinforce subjective opinion and/or experience. A recent reddit post by SanjiWatsuki discusses some measurements of many of today's top headphones. SanjiWatsuki's report is interesting because the measurements seem to track fairly well with the headphones that are most often mentioned as top performers on Head-Fi.org. As is now common, I find Tyll Hertsens' comments a useful reality check.
