How important is it for you to attain a holographic image?

Are you looking for opinions or are you looking for the means to attain it?  Three dimensionality in your soundstage is possibly most effected by (my descending order?)
1. room acoustics, 2. speaker placement, 3. near field listening (or otherwise), 4. and speaker design.  If these things aren't right for your room your electronic choices may be a mute point.
Read, experiment, make adjustments, listen, be patient.  I use a combination of Corner Tunes, Tube Traps, and Bybee products.  Great results...

I'm 65, been playing with this stuff back when we use to get the digest sized 'Audio Mart' in the mail every month. The fun we had with the anticipation of looking at those ads every month. 
To continue our discussion: I would simply like to state that the more I can control my rooms 'interference' with the original signal being launched from my speaker driver, the more stuff I hear in my music when I listen. Those interesting comments we make to ourselves like 'I never heard that before'. I was never really trying to get the holographic effect in my sound stage, quite honestly I noticed it just happened when the room quit interfering...
