Hello everyone

My first post here. Very recently I have become obsessed about audiophilia and exceptionally realistic sound quality from various sources (car system, portable audio player, etc). Now I am looking to buy my first ever audiophile equipment for my lounge (home), and budgets are limited. Can you guide me to the cheapest way of entry into audiophilia? I am not mentioning any price range because I have no clue about the cost of the cheapest equipment I can get new that counts as Audiophile grade!

Cheers
