Speakers with Depth Layering abilities


It seems we all know speakers that provide depth; depth layering is a bit different. I don't notice that many speakers do that. They give depth, but you can't tell who's on first, and who's on second, so to speaker, just that there's a row of violinists in the front and a bass drum in the back, and all the other instruments are in between.
What are the best speakers have you heard that actually layer the rows of musicians front to back? Do any of the Hale Design speakers or the Alon speakers do this?

In TAS, back in issue 68, HP averred that the "IRS, the Magnepans, the quads, the Martin-Logans designs, and even, yes, the Avalons, the Thiels and the Mirages" provide a "...layered field of depth."

It would be nice to know which speakers, given all the money we spend on our electronics, give the audiophile thrills, not to be confused with the musical thrills of a performance. Even in the audio mags, TAS itself, as well as Stereophile, there's little notice of the speakers or other electronics ability to provide this.
So. Whatcha got? What other speakers do this?

Can a speaker with bass depth ,bring out a recording that had none.These then would be great speakers  and highly sought after.
Of course Thiels, Vandersteen and Dunlavey... all first order, time and phase coherent wave launch, minimum baffle, no goofy crossover slopes with midrange wired out of phase, excellent impulse response that starts with the wave heading the correct direction, and in the case of Vandersteen’s pistonic drivers. There are others, as noted the Spica was very capable
I want to point out that the room matters a great deal here.  In terms of depth, what is between and behind your speakers matters a great deal as well as what is behind your head.

Of course, narrow dispersion speakers also have an advantage with less interference of the room before you hear the signal, but a good sounding room is paramount.
