Arcam SA45 Streaming Integrated Amplifier

About The Arcam SA45 Streaming Integrated Amplifier

The Arcam SA45 is the all-in-one streaming system for the dedicated music lover. It includes hard-won technologies for preserving the most delicate sounds and reproducing music with all its subtleties, nuances and excitement intact. Expertly crafted in Cambridge UK, it is born of Arcam's best integrated amplifier, the Arcam A49. With fully balanced digital and analogue audio paths, an all-new digital audio and streaming platform, new linear toroidal power supply design, new user interface and new app, the SA45 is a comprehensive powerhouse of music.

Exquisite sound quality has been achieved through thoughtful engineering of a new 6-layer digital audio and streaming platform which includes a ground plane through the entire board to keep noise and interference away from the sensitive audio components. These components include the latest Hyperstream iV DAC topology from ESS, in a balanced configuration with advanced Jitter elimination. Sound quality is enhanced further with a new linear toroidal transformer power supply design that drives the entirety of the internal operation with lower noise, and a switching supply that only operates for peak efficiency when in standby.

Building off decades of innovation, Arcam's 180 Watt 5th generation Class G amplifier design is meticulously crafted so you can expect the best sound quality and dynamics from what has always been a better sounding, and more efficient Class of amplifier. New components and materials have been painstakingly analysed and reviewed to ensure uncompromising sound performance.

Up front, the SA45 features a large, bonded 8.8" high-resolution display to show album artwork and metadata which is clearly legible from the comfort of your preferred armchair. For playback, an inclusive feature set supports most smart phones and tablets, as well as popular streaming services. Connecting the SA45 to your home network with Wi-Fi is quick and straightforward with the Arcam Radia App. Once connected, enjoy instant playback using Apple Airplay, Google Chromecast, Spotify Connect, Tidal Connect, and Roon.

The Arcam SA45 is the ultimate high resolution audio solution. With outputs for subwoofers, along with Dirac Live Room Correction, the SA45 has the flexibility to deliver exceptional sound, in any room, with your choice of speakers and subwoofers.
