Also there's no guarantee that listening to the mixing or mastering system will provide more (or less) enjoyment than one's system and room. As you say, it's a matter of preference.Isn’t that the argument you use against objectivists? If you hadn’t cherry picked my post it should have been clear that I don’t fall into that camp.
I couldn’t give a flying fig if what I hear is defined as accurate as long it gives me an “illusion” to my ears of performers playing music in front of me. Quite obviously what I hear is highly unlikely to sound the same as in the mastering session let alone the concert hall, but if the recording and hifi fool me into thinking I’m listening to the original performance, particularly with small scale acoustic classical, than job done. The whole thing is an illusion and it is what we think we hear that really matters.
Some may like their hifi to add a touch of flavour, others not; neither is right or wrong, so much as being what works for any individual.
