I'm later to the party but Fleetwood Mac the album Rumours, Michael Jackson Thriller, Pink Floyd Pulse , Ledisi Vaya con Dios, Diana Krall etc are cds I pop in to see what a stereo can do. Blues works as well and of course Metallica though not all albums. I recently got a stereo set up and have been trying to expand my musical tastes. Also hugely matters what kind of room you are listening to music in.
