FWIW, in my limited experience I have come to believe that the sense of PRAT has more to do with any components ability the recreate the initial or leading edge of the note, get the rise time right and you've got half of the battle won. Then get the decay time right and you've got the ability to sense PRAT, assuming its on the recording in the first place.
Now, get that signal thru all your stuff undistorted (perfectly resolved, without hyped detail common to much that is called 'resolved') and you've got great imaging (potential) as well. Every thing in the system contributes to this effect but probably the last place I would think to look for loss of PRAT otherwise available would be in a CDP/Transport-Dac unless it had tubes. JMHO.
