Purely personal opinion and may be controversial:
Depth and layering means you need coherence.
Full range speakers with no crossovers will give you that.
They wont play loud, no deep bass, no top end, but they convey space.
Other than that you'd be looking at speakers from YG acoustics, Avalon, or to a certain extent Wilson.
JM Lab Utopia Be's will do it too, but crossover mods necessary.
