Although I own a couple Schiit products, with which I am pleased, I hate their site because of my sight. The black background with light (whitish) lettering is way too hard for me to read. I avoid such sites, as much as possible, so I won't be attempting to read their take on tone controls.
My own opinion, which is the only one in this thread that counts, is that I don't need them. I know this because, even when I have them, and even when I've tried them, I always ended with them either defeated, or in neutral.
If I ever do decide to use equalization, then I will most likely use it for room correction with one of the many gizmos (with software) that do it. However, one may well argue that setting up dual subs is EQ-ing, in which case I do use it. But not bass/treble controls, or an equalizer. Again, mine is the only opinion that matters.
