Rmihai, I'm sorry but for me this is simply too broad a question to post any meaningful response. There are many resources available on the web to help people begin to explore classical music.
But, to be more constructive, I'll just offer some links to some previous posts about great classical music available here in the archives. These link to some of my answers and folks can simply look through the rest of the particular thread for great recommendations from others.
Classical Fans, I need advice
Best Sounding LPs (classical)
Best of the Decca Reissues (scroll down a screen to second post)
Amazing Solo Piano Recordings
Medieval-style Music
System Reference Recordings
Hi quality, relaxing classical suggestion?
Quite Strings? (sp)(Great string quartets that are "quiet")
Favorite Choral Music
Choral music suggestions
Violin Concertos
killer violin tracks (cd-only requested)
.
