Message from the Past: We were never against tone controls
For those of us who started being audiophiles a very long time ago, we have a message for you all:
We were never against tone controls. We were against poor sounding tone controls, and many of them were. From bass / treble nobs to 1/3 octave equalizers, they all were almost universally garbage.
That was decades ago. Now things are in some cases much better, or at least, not nearly as bad sounding as a poor recording. Stop using guidelines from the 1980's to decide what to do.
You are not obligated to sit through a performance without adjusting the music to suite your tastes. It’s OK to boost the bass, or turn down the treble for your liking. You have all the permission you need.
