It's never been a better time for frugal audiophiles.
Many inexpensive options:
- using your computer with a $200 thumb drive sized DAC as a source such as Dragonfly or Meridian Explorer 2
- subscribing to Tidal (CD quality version of Spotify for $20/month)
- if coming up with a good listening space is tough, consider headphones/earbuds ($50 can provide very good sound)
- for desktop/small room listening several very good active speakers like $300/pair JBL LSR 305
- many good/highly affordable chip amps available
- check out Madisound or Parts Express for speaker kits
No need to invent a speaker, unless you like sawdust.
