Hey russellrcncom,
Great question. Classical, acoustic jazz, piano, and vocals that are well recorded are excellent for getting a "take" on how a piece of gear renders timbres/tonality, spatial dimensions, micro-details, image density, decays and the very subjective domain of sounding natural/musical vs. analytical/electrical.
Historically, some of the best recordings, with a few exceptions regarding pop, rock&roll,and blues, have been classical and jazz music. I use ten recordings at first to get a take on a piece of gear I'm reviewing. My all time favorite tenor sax player is the late great tenor sax player Johnny Griffin, who I had the pleasure to hear in-person more the 50 times in jazz clubs in Chicago. So, I have a live "baseline" regarding what he sounded like in real time. I see how close does the of piece of gear in for review create the illusion of what I heard in person. I then go on using all kinds of genres of music to fill out my assessment of that equipment's performance in the context of my two reviewing systems.
