"DSD-compatible" refers to devices or software that can play or process DSD audio files. DSD, or Direct Stream Digital, is a high-resolution audio format that captures sound with greater detail than standard formats like PCM. This compatibility ensures that users can enjoy high-quality music without losing the nuances of the original recording. To be DSD-compatible, a device must support specific playback methods, such as DSD over PCM (DoP) or native DSD playback. Many modern digital audio players, DACs (Digital-to-Analog Converters), and music streaming services now offer DSD compatibility, catering to audiophiles seeking superior sound quality.
