I think this is a question of semantics. I completely agree that there are all sorts of tastes among people that love music and buy equipment to reproduce it. Just as there are among eaters. However, there are common folks and epicureans. People who love ketchup on eggs and those a carefully prepared Confit de Canard and can tell nuances in it.
An audiophile is a person who is passionate about high-fidelity sound reproduction. They strive to achieve the most accurate and enjoyable listening experience possible, focusing on capturing the nuances and subtleties of music. Sounding like the real thing.
There is a focus on accuracy... there is a target. Lots of folks have consumer products... they are not audiophiles because the output does not approach sounding like the real thing, and they don’t care. Some folks have very expensive systems with a wall of subwoofers... they are not audiophiles. They love music and systems that plaster you against the rear wall, but nuanced accuracy to the real thing is not there. There are folks that are into vintage gear that is incredibly warm and romantic, but is not approaching the real thing. Yes, you are correct, there are lots of tastes out there.
There are also people with incredibly modest system who have spent hundreds and hundreds of hours choosing and tweaking their systems... wires all over the place... who have done incredible things to make their system outperform and sound more like the real thing than folks with a lot more money invested who’s system doesn’t sound real. They are audiophiles.
I think I understand the point of the post... audiophiles have different tastes. With that I must respectfully disagree. Audiophiles are crazy fanatics trying to reproduce music that sounds like the real thing, as accurately and nuanced as possible into the home. Most folks and certainly many on this forum are not audiophiles. Not an insult... doesn’t mean they are not passionate about equipment and the sound they like and love music.
There are other categories of folks. High end enthusiasts for instance, audio.
While I have no doubt that one to the great chiefs of the world, or maybe even the OP could produce a epicurean meatloaf... in modern language meatloaf and beer (as in six pack Joe) allude to simple tastes and big flavors not nuanced, complex and carefully balanced as the audiophile would require in his sound in order to reproduce music well.
