ARCAM - Radia SA45 Streaming Integrated Amplifier

Flagship Performance, Connectivity, and Flexibility: Arcam Radia SA45 Streaming Integrated Amplifier Offers 180Wpc Output, Fully Balanced Digital and Analog Paths, Exceptional Sound, and Much More
All-in-one audio solutions are becoming more commonplace for a host of good reasons, but few such components tout the pedigree of the Arcam Radia SA45 streaming integrated amplifier. Taking cues from the company's flagship integrated unit (A49), the 37.5-pound SA45 delivers enormous power output to the tune of 180Wpc, features fully balanced digital and analog audio paths, and offers generous connectivity that invites you to hook up everything from a pair of subwoofers and a turntable to your TV.
Most importantly, the engineering behind the SA45 knows the difference between letting you hear music — and allowing you to experience it. The distinction largely owes to being able to enjoy the subtleties, nuances, tonalities, and micro-dynamics that make a song or composition sound as if it is unfolding in real time. When those are missing from the presentation, everyone in the room knows they are witnessing a prerecorded program, which are often robbed of the emotionalism and dimensionality you get when hearing an artist live.
Designed in the U.K., SA45 leverages a wealth of all-new components — linear toroidal power supply, interface, app, and digital platform included — to provide you the aficionado-level audiophile performance you deserve. The aforementioned digital platform has six-layer architecture that uses a ground plane through the entire board to help keep noise away from the ESS Hyperstream iV DAC topology, which itself claims balanced configuration and advanced jitter elimination. As for the toroidal transformer? It drives the entire internal operation with satisfying quiet and a switching supply that only activates for peak efficiency when in standby. SA45 also leverages what’s become an Arcam hallmark — Class G amplifier technology, here in its fifth generation — to play with exceptional efficiency, clarity, and smoothness.
Seamlessly compatible with Apple AirPlay, Google Cast, Spotify Connect, and TIDAL Connect, the 5.5 x 17.0 x 15.35-inch SA45 supports up to DSD 256 and 32-bit/384kHz PCM. Ready to interface with your favorite streaming services, phones, and tablets, it effortlessly connects with your home network via WiFi and the easy-to-use Arcam Radia app. Said app further invites you to enjoy Internet Radio, podcasts, UPnP, and USB media (via a USB-A mass storage input). When it comes to versatile connectivity, S45 has you covered in the form of one pair of balanced XLR inputs, two coaxial inputs, two optical inputs, and three pairs of RCA inputs. An HDMI eARC to hooking up your TV, MM and MC phono inputs, and dual subwoofer outputs add to the fantastic flexibility. Want room correction? Done. SA45 has Dirac Live to assist you with fine-tuning your sound.
On the front of the elegant SA45 you’ll be challenging yourself to look away from the large, bonded, 8.8-inch high-resolution display that showcases album artwork and metadata. Bluetooth with Snapdragon Sound and Auracast, a remote control, measurement microphone, and forthcoming Roon Ready ability round out a one-box solution that leaves a lasting impression.
