A lot of words to say that you use a graphic EQ to make corrections, which agrees with my above assertion that mere tone controls for 2, 3, or 5 bands really doesn’t cover the need for correcting room nor recording anomalies.
If you’re serious about correct music reproduction a graphic EQ is necessary at a minimum. If serious about different curves in different recordings a DSP with multiple saved profiles is an excellent tool to select pre-programmed profiles for the different recording and mixing styles. A dynamic-range expander would also be useful (especially if playing from radio, vinyl or other analog media), but that’s likely another topIc entirely.
In the end, tone controls and loudness compensation are both user preference items and do simplify the process of tailoring the listening experience to taste. I’m too meticulous for such, need to start with ruler-flat system response and let the recording and mixing Engineers’ work come through.
Music reproduction in the home is part science and part art. Lean whichever way makes the experience better for you.
