I agree the effects I'm talking about are psycho acoustic. What I'm saying is that not all sound reproduction equipment are equal when it comes to reproducing these effects.
The question is - do components (for example, amplifiers and CD Players) which 'test' the same, sound the same in terms of these qualities (imaging, sense of acoustic space, soundstage, accuracy of the timbre of instruments, attack and decay ... sense of notes 'hanging in the air,' 'bloom') ... they do not sound the same. Some do a better job of reproducing these subtle musical qualities than others.
