I have all 3 Schitt EQs and the Loki mini is just OK I haven’t used mine in a while the Lokius is wonderful, especially with full-range driver loudspeakers. The Max is the better-sounding eq. Remote is nice to adjust sound at the listening position. Still, I would say most systems wouldn’t benefit from the EQ. But if you have room issues, your hearing is failing, or you have a speaker like a full range or music that could use a bit of EQ to sound its best. They can be very useful.
