ARCAM SA45 Streaming Integrated Amplifier

The ARCAM SA45 is a flagship-level streaming integrated amplifier designed for high-performance HiFi systems where powerful amplification, high-resolution streaming and advanced room optimisation are required from a single component. Featuring ARCAM's 5th-generation Class G amplification, the SA45 delivers an impressive 180W per channel into 8 Ohms and 300W per channel into 4 Ohms, providing substantial power and control for demanding premium loudspeakers and larger listening spaces.

The SA45 features fully balanced analogue and digital audio paths, supported by a newly designed linear toroidal power supply and a six-layer digital audio and streaming platform engineered to minimise noise and interference. The latest ESS Hyperstream IV DAC topology is implemented in a balanced configuration with advanced jitter elimination, while high-resolution network streaming supports audio at up to 32-bit/384kHz. A large 8.8-inch high-resolution front display presents album artwork and playback information clearly from across the listening room.

Built-in streaming provides direct access to Spotify Connect, TIDAL Connect and Qobuz Connect, alongside Roon Ready, Apple AirPlay, Google Cast, UPnP, internet radio and podcasts. Wi-Fi and Ethernet provide network connectivity, while Bluetooth 5.4 with Snapdragon Sound, LE Audio and Auracast adds flexible wireless playback and transmission options. The ARCAM Radia app handles initial network setup, presets and access to supported online audio services.

Built-in Dirac Live Room Correction allows the SA45 to optimise playback for the acoustic characteristics of the listening environment, while dual subwoofer outputs provide flexibility for advanced 2.1 and 2.2-channel systems. Traditional sources are equally well catered for with three RCA inputs, a balanced XLR input, dedicated Moving Magnet and Moving Coil phono inputs, HDMI eARC, coaxial and optical digital inputs and USB media playback. Combining powerful Class G amplification, comprehensive streaming and room correction in one chassis, the ARCAM SA45 is designed to become the centrepiece of a reference-quality modern HiFi system.
