SA45 Streaming Integrated Amplifier

The ARCAM SA45 is an all-in-one streaming system for the dedicated music enthusiast, integrating advanced technologies to preserve the finest sonic details. Expertly crafted in Cambridge, UK, it is inspired by the renowned ARCAM A49, featuring fully balanced digital and analogue audio paths, a new digital audio and streaming platform, a linear toroidal power supply, a revamped user interface, and an all-new app.

The SA45’s six-layer digital audio and streaming platform is designed to shield sensitive audio components from noise and interference. At its core is the Hyperstream iV DAC from ESS, configured in a balanced architecture with advanced jitter elimination. Complementing this is a linear toroidal transformer, driving the system with minimal noise, while a switching power supply activates only in standby mode for peak efficiency.

Leveraging decades of ARCAM innovation, the SA45’s 5th generation Class G amplifier ensures superior sound quality and dynamics, with rigorous component selection for optimal performance.

A striking 8.8" high-resolution display shows album artwork and metadata, clearly visible from any seating position. The system supports various smart devices and streaming services, with seamless connectivity to Wi-Fi via the ARCAM Radia App. Instant playback is available through Apple Airplay, Google Cast, Spotify Connect, Tidal Connect, and Roon.

The SA45 is the ultimate high-resolution audio solution, offering subwoofer outputs and Dirac Live Room Correction for flexible, room-optimised sound with any speaker setup.
