Arcam SA45 Streaming Integrated Amplifier
SA45
The Arcam SA45 is the ultimate all-in-one streaming system, purpose-built for the dedicated music lover. Drawing on decades of engineering expertise, it faithfully preserves the finest sonic details—capturing every nuance, texture, and emotion in your music. Expertly crafted in Cambridge, UK, the SA45 inherits the DNA of Arcam’s flagship integrated amplifier, the revered A49. It features fully balanced digital and analogue audio paths, an all-new digital audio and streaming platform, a refined linear toroidal power supply, a modern user interface, and a powerful new app—making the SA45 a true high-performance hub for serious music listening.
New Streaming Platform
Exceptional sound quality begins with Arcam’s newly engineered 6-layer digital audio and streaming platform. At its core is a full-board ground plane, carefully designed to divert noise and interference away from the most sensitive audio pathways. This foundation supports the latest Hyperstream IV DAC architecture from ESS, operating in a fully balanced configuration with advanced jitter elimination for astonishing clarity and precision. Further elevating performance, a new linear toroidal transformer supplies ultra-low-noise power throughout the system, while a secondary switching supply activates only during standby for maximum energy efficiency without compromising sonic integrity.
Class G Amplifier Design
Refined over decades of innovation, Arcam’s fifth-generation Class G amplifier design delivers exceptional sound quality and dynamic range from one of the most efficient and musically engaging amplifier topologies available. Every component and material has been carefully selected and rigorously tested to ensure absolute sonic integrity—pushing the boundaries of what Class G amplification can achieve.
Features
At the front, the SA45 features a stunning 8.8″ bonded high-resolution display that brings album artwork and track details to life—clearly visible from across the room. Designed for effortless playback, it supports a wide range of smartphones, tablets, and leading streaming services. Connecting to your home network is quick and seamless via the ARCAM Radia app. Once online, you can instantly stream music using Apple AirPlay, Google Chromecast, Spotify Connect, Tidal Connect, and Roon.
