There is a piece of gear that has the specific objective of giving you a more holographic soundstage. It's a processor from a company called BSG (no longer in business) and the model is a QOL (pronounced coal). It has been positively reviewed by Stereophile and TAS and the reviews are available on their websites. When new they sold for $4k which I believe is a large reason why they didn't catch on. You can occasionally find one on the used market for under a grand.
I have one in my system (Krell KSA 300S, KRC-2, Theil CS6 speakers) and I really like the effect. An audio buddy recently stayed at my house for a couple days and he was very impressed by the depth of the soundstage and the placement of voices and instruments. When bypassed, the difference is very noticeable. I use it nearly all the time. Once in a while I encounter a recording that sounds worse using the QOL but that's pretty rare.
If you can find one I highly recommend trying it. If you don't like it you should be able to resell it for nearly what you paid for it so it's a low risk proposition. I like mine so much I bought a second one in case the first one quits working.
