I've used all sorts of equalizers over the decades and have an SAE in my basement someplace...I use a little two channel graphic EQ in a live mixing rack, and some parametric EQ, but otherwise haven't used one in my hifi rack for decades because hey...they generally SUCK, except for the Loki, which when needed is amazing for all the reasons mentioned, foremost being that it's the only EQ I've encountered (I avoid digital domain EQ for home listening, but that's another topic anyway) that is utterly transparent.
