Integrated Amplifiers

Integrated Amplifiers in Hi-Fi Systems

An integrated amplifier receives line-level audio signals from source components such as DACs, CD players or phono preamps, then amplifies those signals to drive loudspeakers. Because both preamplification and power amplification stages are housed together, integrated amplifiers reduce the need for separate components and additional interconnect cables.
Common source components connected to integrated amplifiers include digital-to-analogue converters (DACs), CD players and streaming devices.

Integrated amplifiers are available in a range of designs, including solid-state, valve-based and digitally equipped models with built-in DACs or streaming capability. Selection depends on system requirements, speaker compatibility and whether additional features such as digital inputs or phono stages are required.
When using a turntable, an integrated amplifier may require an external phono preamp if a phono stage is not built in.
