Being a big fan of mid to late 20th century, and contemporary classical music (you know, the 'thorny' sounding stuff), I have a quite a few vinyl recordings on Nonesuch records in their "Spectrum: New American Music" series.
These were considered a budget label release at the time (late 60's to mid 70's). But despite that, I don't believe I have any other recordings in my collection, on any format, that creates such an amazingly tangible soundstage and 3d image within that soundstage.
If you ever want to test a system for how well it images and creates a soundstage, get one of these recordings. Most good used records stores will have copies.
Just to give you an idea what to look for, these recordings all have a similar look to this -
