Are you trying to make a permanent fix for speaker room issues, or trying to fix up various recordings that are too hot sounding? If you are trying to fix up individual recordings, something like the Lokius is very effective because it is easy to dial in a quick fix with its wide band controls. If you are trying to fix your overall speaker room interaction, a good digital room correction package can give amazing results if you already have a decent room.
I think you will find that vintage equalizers will not sound transparent compared to Schiit equalizers, and the more bands will be harder to dial in for individual recordings. I've tried a number of equalizers in the past, and never found anything that sounded transparent until I started using digital EQ some 15 years ago or so. When I first tried the Lokius, I was shocked that something so inexpensive sounded so much more transparent than some very expensive equalizers I had tried in the past. I haven't tried the Loki Max yet, but even the Lokius is great for fixing up tough recordings.
