I’m a jazz and classic rock guy. Very few classic rock albums make the testing cut, although Dark Side of the Moon is one of my go-to test albums. Also Hot Tuna Live at the New Orleans House Berkeley. But for real critical listening to test new components, my go-to choices are Patricia Barber - Companion XRCD, and especially the second cut, Use Me, which has a killer stand up bass intro. My other go-to jazz album is the remastered Jazz At The Pawnshop — extremely well-recorded. For interesting live imaging, I also use Shakti’s first album. John McLaughlin and Zair Hussein on tablas is sublime!!!
