Best Headphones: Open-back planar magnetics (e.g., Hifiman Sundara or Audeze LCD-2) reveal the spatial imaging of The Fog.
Best Speakers: Studio monitors with a flat response (e.g., Yamaha HS8) will let you hear the sub-bass drop in Biblical that MP3s often lose.
Software: Use foobar2000 or VLC (with WASAPI exclusive mode) to bypass your operating system’s audio mixer. Play Victory Over the Sun and listen to the distortion on the bass guitar—it is intentional, textured, and glorious.
