First it is so evident that if spatial information is not encoded rightfully from the recording engineer NOTHING will ressuscitate this information lost for ever...
Then the recording is not a factor which we can control. I did not even mention it.in the right system /room no album present the exact same soundstage. This difference correspond to each recording. We speak about a system/room able to create more so or less so an interesting soundstage for sure already encoded in the vinyl or dac.
@livingwellinco : "The soundstage is unreal." Really, man!
Now saying that only reveal you know nothing about the relation between physical acoustic and psycho-acoustic... And the importance of sound direction for evolutive survival of man as a prey ...And hunter... And sound direction perception ( and the impediment of stereo crosstalk )is the COLLECTIVE perception which our brain create the soundstage impression because of the specific acoustic parameters between 2 speakers and room. Do you call colors illusion? It is not even wrong, it will be an ideological abuse of words.
The soundstage is a real perceived phenomenon which can vary for each of us even with the same system/room... But it is there...
