Can a system sound too Holographic?

I had my room over-treated.

The result was "too holographic".  Lost the center image and the sound was all over the place.  So much so it made listening very weird.

Added back some reflective surfaces and the center image came back.  Soundstage and imaging were greatly improved.

What you're describing is not holography, because it has nothing at all to do with the loss of a center image, or any other image for that matter, quite the opposite. You seemed to be experiencing phase issues which are an entirely different thing.

good point @roxy54

i remember several years back, i bought a preamp from a nice older gentleman locally, he insisted i come in to hear his system, of which he was very proud

i sat there, big focals driven by $15000 mcintosh hybrids, in a beautiful home in classic styling... then he played music, it was all phasey, sound coming from the sides, hole in the middle -- so looked at his cabling, sure enough one speaker had black on red and vice versa... i asked him to sit down, i swapped the connection... asked him how he liked the sound, his face turned red, he said, ’’whaddidja do? holy moly’ ... he was more than a little embarrassed, but happy and thankful ... lol

There is Zero chance what your friend describes is the result of a ‘Footer’ change! There just isn’t that much of an affect that comes from isolation unless it was SO bad before that his system surely wasn’t ‘holographic’ to begin with!! Tweaks are tweaks and they do not results in a sea-change unless a severe issue already exists.
