It‘s not just the speakers. Good isolation of the components and cabling, I found helps to sharpen and focus the images. My current system, depending on the recording will paint a 3D soundstage that goes beyond the walls- if I close my eyes or turn out the lights. It was fun af first. I could close my eyes and hear the large sound stage and then open my eyes and see the walls cutting right through the band. Now I can hear the full sound stage mostly with my eyes still open.
Eric Clapton records are a good example. On one he is standing. His voice is about 6 feet high and his guitar is about 3-4 feet high. On the Unplugged album, he is sitting and his voice is 4 feet high while his guitar is 3 feet high. Several recordings do things like that. Drums will be about 2-3 feet high and cymbals just a little higher up. Other albums have everything at the same height- instruments and voices. Some albums are a flat wall of sound while most have instruments and voices in various positions front to back as well as left to right. Some Chorale pieces have voices from floor to ceiling- very dramatic. Well recorded piano is interesting. Sometimes the piano seems placed at a diagonal and sometimes it is at a right angle. I can think of one recording where the piano is left to right on the stage. Makes it feel like the piano is almost in my face. Just depends on the recording.
I have used the Roger Waters track for a few years as one test for speaker placement. My current speakers put the dogs at the extreme right far away and the talking man at my extreme left about 8 feet away. I hear sounds behind me now and then. Don‘t really care for that.
Vinyl used to be the best for a big open soundstage and images but my current digital side does the job just as well as vinyl now.
