Welcome!
There's never been a better time to get into audio. Internet streaming of CD quality music (Tidal, Qobuz, Amazon HD) allows anywhere access to millions of albums for $20/month or less. A NAD Node 2i ($550) provides streamer, operating system, DAC, and preamp in one small easy to use box. And active speakers (built-in amps for each driver) offer wonderful sound at prices as low as $300/pair (Kali LP6 is a very steady example). This sound quality at this price and convenience was unimagined 20 years ago. Of course the sky is the limit if you want lots of big impressive boxes with better sound. But most audiophiles ignore the importance of the room (don't go small/squarish, try to insulate, think about treatments).
