To the folks who believe that we ALL hear the same, I am posting a link to a scientific study. There are other scientific articles, if you keep your minds open, that are available on the net, if you search:
We're All Hearing Differently, and Here's the Proof
There are so many differences when it comes to different humans. Hence one should not assume that what one hears, the next person hears the same. Maybe it our "hearing" that makes us audiophiles - that our family/friends and acquaintances do not have. Rely on your own "hearing" senses, rather than checking out the measurements. Finally, if it does not make it a difference to you, then good for you - save that money instead of upgrading the components and buy music or spend on something that you find worthwhile spending on. But folks should stop preaching that people should rely on measurements to know the difference.
