Arcam SA45 Integrated Amplifier Black

SA45 Integrated Amplifier with Streaming

The ARCAM SA45 is an integrated amplifier with internal streaming dedicated to music lovers who do not accept compromise. The technologies used are the result of years of study and research, to preserve the most delicate sounds and reproduce music with all the little nuances that make it exciting. Designed in Cambridge, UK, it uses a brand new digital audio and streaming platform with fully balanced digital and analog audio paths, a new power supply circuitry with a toroidal transformer, a new and more intuitive user interface and a new App.

The sound quality is made possible by a new digital audio and streaming circuitry, with a 6-layer layout, which benefits from a full ground layer to keep noise and interference away from the most sensitive audio components. These components include the latest ESS Hyperstream IV DAC topology, in a balanced configuration aimed at eliminating jitter. Sound quality is further improved thanks to the new power supply design which uses a linear toroidal transformer capable of fully handling the power demands of the power stage.

Based on decades of innovation, the design of the fifth-generation Class G power stage has been meticulously crafted, ensuring the best sound quality and dynamics, which have always been the prerogatives of Class G amplification. The components and materials used have been carefully selected to ensure maximum performance. Power output is a generous 120 watts per channel into 8 ohms and 220 watts into 4 ohms.

On the front, the Arcam SA35 features a new 8.8" high-resolution display for viewing album artwork and metadata. Connecting the SA35 to your home network via Wi-Fi is quick and easy using the ARCAM Radia App. Once online, you can enjoy instant playback from popular streaming services via Apple Airplay, Google Cast, Spotify Connect, Tidal Connect and Roon.

Dirac Live room correction is also featured, and it comes with a measurement microphone and remote control to make room calibration easy with any speakers or subwoofers you use.
