First hifi system and starting a CD collection. What essential albums can be found in bargain bins and thrift stores?

This is such a wonderful hobby! After years of playing music on headphones and computer speakers I got myself a decent system. I had a large collection of CD's but I sold them for cheap years ago. Luckily I ripped them to mp3 first but after a harddrive crash I reripped every single one of them to flac so essentially I still have all my music.

I got a free CD transport with my system (and an electric scooter but that's another story) and I could sell it but I like the idea of collecting and playing discs again. I won't get all my older CD's back but I would love to get a small core collection of popular audiophile recordings that can easily be sourced second hand.

So what albums should I look out for? What albums have been sold a lot so I have a chance to find them in a thrift shop? I think albums of Sade, Dire Straits, Pink Floyd, Fleetwood Mac can be easily found but I'm not familiar with the good ones. What else is there? What would my master audiophile shopping list need to include? Thank you for any suggestions!!
