Super Audio CDs (SACDs) are a high-resolution audio format designed to provide superior sound quality compared to standard CDs. They use a different encoding method called DSD (Direct Stream Digital), which captures audio in a way that more closely resembles analog sound. This results in a richer and more detailed listening experience. SACDs can contain both high-resolution audio tracks and standard CD tracks, making them compatible with regular CD players, although to enjoy the full benefits, a dedicated SACD player is recommended. Many classical and jazz recordings are available in this format, appealing to audiophiles seeking enhanced audio fidelity.
