Blind Lossless Audio Test (abx.digitalfeed.net)

And here's another one: https://www.npr.org/sections/therecord/2015/06/02/411473508/...

The James Blake one was the most difficult. With my heaphones and dac/headphone amp combo I got 80%, with the test stating there is 0% likelihood that this result was chance.

High quality audio is snake oil. It's primary value is to sell you things you don't need. So much has been done to music before you get it there is no real thing to hear. Just enjoy the music, not the fidelity.

I wonder whether doing this on Chrome on macOS (+ DAC, headphones or whatever your setup) plays the actual files at their best resolution

I feel like Apple Music Hi-res + my DAC and headphones sounds way better than either of the samples from the test
