Clarity has somewhat of an effect on imaging. IMD damages something good about audio that I have problems actually describing, and it doesn't take much of the IMD to do the damage. IMD is one of the non linear distortions that is not measured on the typical AP analyzer FFT. Inter modulation distortion is not the side band/harmonic spectra surrounding a pure tone rather depends on interactions between tones. Think about distortion/soundstage breakdown when too many instruments are playing at the same time. Superdad, sandyk, semente and 1 other 4 Custom room treatments for headphone users. Link to comment

Your “system” works for you to achieve your own pleasure regardless of the recording — your pleasure is not a function of the specific musical input, rather the efforts you make to arrange your “rig”. That’s all well and good but doesn’t help those who are seeking an audio reproduction system which reproduces the recordings. Teresa and Superdad 2 Custom room treatments for headphone users.

This perhaps explains why equipment which produces high quantities of IMD can still be popular. I can’t say that it’s just IMD but I’ve also compared rock (eg Yes:Roundabout) across different systems inclusive different live arenas and I’ve heard the music “breakdown” during complex passages. sandyk 1 Custom room treatments for headphone users.
