Speakers that excel at depth/layering/space

mbl if you have a suitable room.

dynaudio contour 1.3mkii in smaller rooms.

also ohm walsh properly matched to room.

as you can tell, integration of speaker into room is key to get good imaging depth imho.

Sounds like someones been smoking those left handed cigarettes .

"Width and openness is one thing, but depth with layering and space from front to back is much rarer."

It's not rare at all with electrostatic speakers.

I'm wondering how much electronics like the Mcintosh amp was contributing to this effect.

I thought about this more and a soundstage that starts at the speakers and then presents back from the plane of the speakers is part of what I was hearing. Also, very focused and not a huge soundstage (as in not super wide or forward) seems to contribute to this 'focused, layering effect.

Besides the PSBs, I have heard this with Audio Physic Caldera (albeit set up in the AP prescribed position) and Innersound Kaya, but both of those are very exceptional in their design and set up technique and have a one foot square sweet spot.
