Any Alan Parsons Project record is good, especially Pyramid and Eve.
Yes, Pyramid is excellent. When I sold or gave away all my LP albums, that is one out of the three I kept for a souvenir. I haven’t listened to vinyl in about 30 years unfortunately.
Supertramp recordings always sounded very polished, too.
If ya wanna test stereo speakers I suggest using Queens “ The Prophets Song” from the Night at the Opera album.

Women mystified and confounded me just as much then as they do today.
