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

When I listen to the Hollywood Saxaphone Quartet ( https://www.amazon.com/Hollywood-Saxophone-Quartet/dp/B00CHQKNNO/ref=sr_1_1?ie=UTF8&qid=15464207...
or Doc Evans "classics of the 20" on Audiophile AP 50, https://www.amazon.com/Classics-20s-Red-Vinyl-Evans/dp/B002LO6RAA/ref=sr_1_5?s=music&ie=UTF8&...(mid-50s mono LPs, the saxes aren't piled up in the center but spread across between my speakers and the band is spread out as well with instruments placed 3D in between depending on where they were recorded.  So many of my mono LPs have depth and spread out performers, as if they were stereo, it fools even die-hard stereophiles.   Maybe I just have a mediocre audio system that falsifies mono into omni-sound.  Although I doubt that because true stereo sounds great as well and my speakers are definitely non-omni types.  Just ask Oregonpapa since his system is similar type and similar sounding.

I’ve been known to leave the mono switch on after playing a mono album an not notice for a day or two of stereo recordings so probably not a major issue for me.

What I do dislike is when the sound dives for the closest speaker when I listen off axis as I’m often not listening alone, it’s possible to set speakers up so this doesn’t happen and the image stays stabe but the positioning needs to be quite precise. I found Sumiko Masterset quite useful for this.

Yeti, I know it's possible to have a very wide "sweet spot", but very expensive; I don't have it, mine is the same as yours.

Fleschler, probably none of our systems are identical, and yours can do things mine wont do.

yeti42  It helps to widen the sweet spot if you turn your speakers inward so the axis' crosses in front of your head when you are in the sweet spot.
