My thought is that perhaps most buyers of Magico and other expensive speakers tend to be very busy, successful people who don't have much time to allocate to leaning about, much less setting up, an active speaker. They just want to buy a speaker they're convinced is at least to some extend SOTA and place them in their listening space. They just go to AXPONA or a high end dealer and try to find speakers they like the sound of and can hook up to their existing amplification and be done with it.
I know of a billionaire (whose parents came to America with education but no cash in their pockets; so it’s a story of luck and hard work). Anyway, even as a triple digit millionaire, he had the same problems we have as ordinary people. Getting the best room for listening wasn’t easy. His main listening room was still a shared family living space. As a billionaire, he has since built a dedicated listening room.
Anyway, at this level of play, the high end dealers are going to be doing the setup for you. So there is no need for tweaking or hooking up to existing amplification.
If you look at these Magico‘a (done before their NFS) you can see it’s pretty good.
