Try to get LP records whatever you want to listen to. Digital is no good for any kind of music and even worse for classical to the point of becoming ridiculous for big orchestra.
Carmen was an excellent suggestion for opera though it matters who performs. Carmina Burana by Orff is great too. Then of course the usual names - Bach, Beethoven, Musorgsky, Mahler, Paganini etc. With classical it is very important who performs and conducts. I am not big fan of this kind of music so others will guide you more specifically including advising you to get particular performances and LP editions.
The power of orchestra can be incredible.
