I get the feeling that a lot of these holography systems that have appeared over the years are aimed at those who have a lack of resolution in their systems- and can stand listening to an effect, rather than the music.
FWIW: It is easy to add holographic effects or wide soundstage by using a flanger or adjusting phase between two channels - guitar folks know this all to well - there are literally hundreds of sound effects. Another effect is reverb circuitry like Harmonix
There is a science behind these effects too but it is too much to go into here. I share Ralph's opinion though - I prefer not to add extra effects to the CD's I play - even if some of it on some tracks can be pleasing addition/change.
