Better Sounding Systems, Objectivists or Subjectivists?

Surrealists - why settle for reality when you can have so much more?

When these two camps retire to their listening rooms, which school of thought tends to get better sound?

That's the wrong question because they are likely to define "better" differently.  The real question is "Which school of thought tends to be happier with their sound?"    

How does the music make you feel and is it inline with how you wanted to feel at the time? Rather than listening for being able to hear this breath or that cymbal hit, how does it feel when you listen? That will tell you what sounds best. If it measures well and you feel good listening to it, doesn't make you tense (unless excitement all the time is what you're looking for) and you can listen for long periods without wanting to turn it off, you've got the best of both worlds.  Because of how mental this hobby is, one day something can sound great and the next day, just good. It's why auditioning equipment shouldn't be swapping stuff out quickly. Listen for a while, then listen the other way for a while.  Which one made you feel better? No difference? Buy the cheaper or better looking or more expensive or whatever your additional criteria is besides sound.
