ARCAM Radia SA35 & SA45 Integrated Streaming Amplifiers

ARCAM Radia SA35 & SA45 

For decades, British audio heavyweight ARCAM has been synonymous with exceptional, musical amplification. But as our listening habits have evolved, the demand for "just add speakers" systems has skyrocketed. Enter the ARCAM Radia SA35 and ARCAM Radia SA45—two premium, all-in-one streaming integrated amplifiers designed to deliver uncompromising audiophile performance without the clutter of traditional separates.

If you are looking to simplify your high-fidelity setup without losing sonic magic, these two powerhouses deserve some serious consideration.

Under the Hood: 5th-Generation Class G Power

At the heart of both the SA35 and SA45 is ARCAM’s signature Class G amplification. For the uninitiated, Class G acts like a hybrid engine. At lower listening levels, it runs in pure Class A, offering an incredibly sweet, distortion-free, and natural sound. When the music demands sudden, massive dynamics—like an orchestral swell or a heavy electronic bass drop—a secondary power rail seamlessly kicks in.

The transition is completely invisible to the ear, giving you effortless muscle alongside absolute subtlety.

  • The SA35 delivers a robust 120W per channel into 8 ohms.

  • The SA45 steps things up to a commanding 180W per channel into 8 ohms, backed by a fully balanced digital and analog audio path.

Modern Aesthetics Meet High-Res Streaming

Gone are the days of boring HiFi boxes. Both units share the stunning, sleek aesthetic of ARCAM’s Radia series, complete with subtle yellow accents and a matte black finish.

The first thing you’ll notice on the front panel is the crisp, full-color display. The SA35 sports a vibrant 6.5-inch screen, while the flagship SA45 boasts a massive 8.8-inch display. Both screens beautifully showcase album artwork and metadata, making them easily readable from the comfort of your listening chair.

Behind the glass lies an ultra-modern streaming platform. Managed via the smooth ARCAM Radia app, both units natively support:

  • Spotify Connect & TIDAL Connect

  • Qobuz

  • Apple AirPlay 2 & Google Cast

  • Roon Ready integration

Room Correction and Connectivity

No matter how good your amplifier is, your room's acoustics will always affect the final sound. ARCAM addresses this by embedding Dirac Live Room Correction into both units, complete with an included calibration microphone. Dirac actively measures your room and corrects acoustic anomalies, resulting in tighter bass, sharper imaging, and pristine vocal clarity.

Connectivity is incredibly comprehensive. Alongside traditional digital inputs and line-level inputs, vinyl enthusiasts get dedicated, high-quality MM and MC phono stages. There is even an HDMI eARC port, allowing you to route your TV's audio directly through your high-end stereo system.

Which One is Right for You?

Choosing between the two comes down to your space, your speakers, and your budget.

The SA35 is a lush, un-fatiguing, and deeply musical hub that will happily anchor most premium home audio systems. However, if you have a massive living space, power-hungry speakers, or simply want the absolute pinnacle of scale, body, and low-end authority, the flagship SA45 is the no-compromise juggernaut you’ve been waiting for.
