You might want to browse the Cheap and Cheerful circle. It serves as an entry to audio.
For instance, here's an example of a very good quality system:
- Monthly subscription to Tidal ($20 or less) gives access to 50 million+ CD quality albums

- JBL 305 Mk II ($300 MSRP) are active speakers (built-in power amps) that sound wonderful and can fill a medium sized room
