Depends on the recording. The Boult recording of The Planets on EMI contains enormous depth, the tympani, snare drum, and triangle sounding much further away than the wall behind my planars. Way, way, way at the back of the orchestra, up on risers (line-source loudspeakers do height well).
The closely-mic'ed voices, acoustic guitars, dobro, mandolin, fiddle, and upright bass on Bluegrass albums sound right in front of me---reach out and touch 'em, as they should. Most Pop albums sound artificially-created, as they should. Plate reverb trails in the channel opposite the voice or instrument! "Imagining" on most Rock recordings is absolutely contrived; each sound is on a separate channel, a stereo pan-pot used to place the sound somewhere between hard-left and hard-right. Reverb is also used to create the illusion of depth.
How can a recording contain depth, true imaging---a soundstage, when there was none to begin with, and the mics are mere inches away from the instruments? Back to mono! ;-)
