The majority of music apps on devices have their own "custom" EQ settings. It's probably not surprising that they all sound a little different, even if everything around them is digital and "exactly the same signal". It very much gets into matters of preference and taste - people love to abuse the word "objective" when there's not really any objective measure. Sure, you can say the dominant frequency of a note on a piano is correct or not, but the rest? More due to taste. The preferences can often be "shared" by culture associating specific quirks with "better" or "worse", but that's still just preference. How many musicians intentionally use older techniques or "worse" equipment specifically because of the sound they create? Look at the culture around Synthesizers, for example. Is it really crazy to believe that the "perfect" concert piano tuner example in the article is just a preference in a shared culture of "Concert Pianists"? And are we then really losing something that's "better"? Or just another cultural artifact that may fade with time? We're not "losing" things any more than any cultural shift is a "loss".
