Subjectivity is only what you think.
An opinion.
An impression.
Something depending on no more than a casual mood.
Something that can change from month to month, week to week, day to day.
Or sometimes, from even hour to hour.
A never-ending merry-go-round way of spending vast sums of money chasing an impression only to eventually find yourself back back to where you started from.
After which you will find none of the eager money collectors prepared to accept liability for encouraging you and leading you on this time and money consuming wild goose chase.
They will have moved on to the next mug, err I meant to say, enthusiast.
Not that I know anyone like this.
Pause for laughter.
Objectivity is an attempt to discern what's actual.
Something measurable and repeatable.
A way of comparing the fidelity of the original recorded signal to the signal being transmitted by the loudspeakers.
It's called progress.
There is no need to be scared of objectivity when it comes to audio playback.
You will lose nothing by having a more accurate reference point upon which to base your listening pleasure.
Why wouldn't you want your playback to represent the recording you are listening to more accurately?
Even better, if you are so inclined and so wish, there's nothing thereafter to prevent you bringing your imagination into play as you listen.
If you don't, you will still have a faithful representation of the recording before you.
