There is a lot that can be measured beyond what we might see in a journal like Stereophile, but it’s not practical, affordable or relevant in many cases.
Our listening rooms are the biggest factor, and of course they are all different. As Al says there are quite a few measurements that give you a good steer if you know what you’re looking for.
Widening the point a bit, some things like ‘stereo depth’ and ‘imaging’ aren’t really a thing that is measurable, and relies a lot on our brains. I’m not sure if that’s strictly psychoacoustics, but it’s definitely more perception than reality.
