A desktop hi-fi signal chain: laptop connected to a small DAC/amp box and over-ear headphones

If you spend your day in front of a laptop and your music comes from that same machine, you already own most of a hi-fi system. What's usually missing is an understanding of the path your audio takes from a file (or a stream) to your ears, and where in that path quality is actually won or lost.

There are situations where, from the outside, everything seems fine. No one is treating you badly. There's no real threat. No tragedy is unfolding. And yet, your body activates: tension, discomfort, irritability, sadness, the urge to leave, a feeling of being trapped.
