Newbie in Classical Music

Hello everybody,
I will not lose to many words about my person in this introduction and cut directly to the chase.
I have noticed that lately my taste in music is beginning to change. I scroll through the radio stations, whenever I am in my car, and can simply not listen to whatever it is they call music nowadays. It feels like it is one and the same song. Like the same ware, in a different package. It does not arouse much feeling in me. It feels like a kind of aggression against my spirit. I want it turned off. On the other side, listening to something like "Voi che sapete" from Mozart let's say... or The ninth Simphony of Beethoven is a real experience. I get excited. By the first one one feels the tendernes and naivity of being a stupid young boy in love for the first time... my heart just feels that state of being...
That was just a short introduction. I am nowhere near to being a fine connoiseur of classical music.
This is why I took the effort, to reach this place. I have been wondering through the "babylonical comercial jungle" of the mainstream internet of today to reach you people. My heart longs for wisdom, for knowledge and I shall walk the steep and narrow path for reaching it.
Please, take me, a son of philistines and teach me the ways of beauty and art.
I shall begin with one first question>
What is the best setup for listening to classical music at my home? Should I acquire a so called DAC and Ampliphier, Headphones or Speakers?
Could you please link a good resource for learning more about the technical stuff so, that I can lay a solid base for my musical education?
Best Regards and thank you in advance for your answers!
