Part 3: The HiFi Experience via ARL (Unofficial vs. Official) I decided to run a test. I have a standard Deezer HiFi subscription. I listened to Steely Dan’s Aja (the gold standard for lossless testing) in three scenarios. Scenario A: The Official App Sound: Crisp, detailed. The low end on "Black Cow" was tight.
