Powerful and efficient

Trust me, 90 watts per channel can be plenty. Arcam uses a linear power supply in the SA20 that provides enough clean, efficient power to drive the most demanding speakers. I heard a pair of Revel Performa F206 towers connected to the SA20 in our large training room, and the results were impressive. I could feel the bass in each track I listened to, and my ears enjoyed every nuance in voices and instruments. 

Versatile Class G amplifier

The engineers who designed the SA20 wanted it to provide the right amount of power at the right time, so your music always sounds exactly as it should. That's why they chose a Class G amplifier, which uses Class A circuitry for low-level signals, then kicks in a higher-voltage power supply for more demanding dynamic peaks. And it does it without adding any crossover distortion or noise.

Convenient connections

The SA20 gives you plenty of options for connecting music sources. There's a Toslink optical connector and two digital coaxial inputs on the back of the chassis, along with three stereo analog RCA inputs. For vinyl enthusiasts, there's a dedicated phono input for turntables with moving magnet phono cartridges.
