Our main article described the basic setup and results of our music streaming test.
But we know a lot of our high-end audiophile readers will have questions about the specifics of what we did. For those people, here are the details. Note again that this is not a scientific test, but rather an informal way of replicating what normal consumers would do: listen to the same song on a few different services, to see what sounds best.
We conducted our test in CNBC's high-fidelity audio "sweetening" room. Professional audio engineers set up all the equipment and operated the tests.
We brought in 15 of our colleagues, asking them to pick three songs each. That got us to 45 total songs played. A few of the colleagues wanted to try a fourth song, so that's how we ended up with 48 possible picks.
Each song was played on three streaming services. Tidal was the high-fidelity choice, along with Spotify and Apple Music. If Spotify or Apple Music happened to crash a browser temporarily, then we swapped in Deezer to ensure that there were always three choices. Tidal never crashed, so that one was always an option.
