Thankfully we're not, but If limited to just one record that has multiple facets, one that I use all the time for equipment evaluation is Finzi's
Intimations of Immortality. (Lyrita SRCS-75) It has a moderately large orchestra with percussion, choir (male and female) and tenor soloist, none of whom are world class but are suited to the music and venue. An HP list favorite early on, Finzi's 45 minute one-movement composition uses Wordsworth's Ode of the same name as his libretto.
Mid-20th C. British. It lacks huge climaxes a la Mahler or Shosty, and of course Finzi is not Beethoven, but sonically many of the audiophile elements are there.

I listen primarily for clarity and flow, how well the choirs sound like groups of individuals singing together, dynamic gradations and timbre from the soloist and particularly from the percussion section. Lyrita seems to have a knack for recording percussion. Some of the singing is done in rounds, so I listen for vocal clarity and articulation as each wave launches over its predecessor.
