Excellent description of "what matters most". While the specifics of "what matters most" may change from one listener to another (and from one designer to another), imo you nailed the essence, which is these two things:
1. A speaker must do SOMETHING so well you can get lost in the music. That something can be timbre, imaging, coherence, slam, PRAT, low-level detail, whatever. But it must do something wonderful.
That’s the easy part.
2. The HARD PART is, the speaker must not also do something so poorly as to ruin the magic and collapse the illusion that its "something wonderful" just created. There are more things that can go wrong than I can begin to list.
Apparently the DeVore O/96’s indeed do their something wonderful and then don’t turn around and do something so poorly as to destroy the illusion. Imo that’s the magic formula, and it’s much easier said than done. Kudos to John DeVore.
As for "accuracy", one of the worst-sounding prototypes I ever made was the one with the flattest response. As I tweaked the design closer and closer to flat, it sounded worse and worse. I pressed on, having faith that the heavens would open once I had achieved flatness. Nope. These days my target curve for home audio slopes gently downward as we go up in frequency, so I guess I don't even try to build objectively "accurate" speakers.
