The Arcam SA45 Streaming Integrated Amplifier stands out as a reference-level solution, combining high-current amplification, advanced streaming capability, and system flexibility in a single, purpose-built design.
 
The SA45 is built around Arcam’s latest-generation Class G amplification, delivering 180 watts per channel into 8 ohms with exceptional efficiency, low noise, and substantial dynamic headroom. This topology allows the amplifier to remain smooth and composed at low levels while providing effortless authority when driving demanding loudspeakers or filling larger listening spaces. The result is sound that is controlled, transparent, and musically engaging across all genres.
Beyond amplification, the SA45 functions as a complete high-resolution streaming hub. Integrated network streaming supports AirPlay, Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, and Roon Ready operation, allowing direct playback from popular services over Wi-Fi or Ethernet without external streamers. Wireless playback is further enhanced with Bluetooth featuring Snapdragon Sound, LE Audio, and Auracast, offering higher fidelity and modern multi-device capabilities.
 
System integration is equally comprehensive. The SA45 includes balanced XLR and unbalanced RCA inputs, a fully featured MM and MC phono stage for turntables, multiple digital inputs, and HDMI eARC for seamless television audio integration. A large, high-resolution 8.8-inch front-panel display presents album artwork, metadata, and system information clearly from across the room, while Dirac Live room correction and dual subwoofer outputs allow precise tuning to your listening environment.
 
Designed with long-term ownership in mind, the SA45 features a rigid, acoustically inert chassis, intuitive control layout, and Arcam’s clean industrial aesthetic—making it as satisfying to use daily as it is to listen to.
