The HiFiBerry DAC+ is a high-resolution digital-to-analog converter for the Raspberry Pi 2 Model B as well as the A+ and B+ models. This product also works with the Pi 3. It is a specialized sound card for the Raspberry Pi, optimized for a specific use case: excellent audio playback quality. This is the standard RCA version, which uses the RCA connectors you are familiar with from your regular stereo system. The HiFiBerry sits directly on the GPIO pins of your Pi, like all Pi HATs, without the need for additional cables, and features a built-in EEPROM for automatic configuration.
