Then there is the issue of the equalizer coloring or distorting the sound even if it is set up properly, which keeps some audiophiles from using these devices.

Equalizers can be used to tailor sound in a way that will more pleasing. This thread has assumed all audiophile cables are designed to tailor the sound. Is the assumption true?
Equalizer like the ones from Behringer have spectrum analyser LED on the slider itself so you can address the problematic frequency without SPL meter even though it won't be as precise but not too far off. You can find baseline setting more easily.
BTW what is the audiophile's objective to use audiophile cable?
