SA20 Integrated Amplifier

  • Class G amplifier for impeccable sound
  • 80W of power per channel
  • 5 analogue inputs including phono stage (MM)
  • 3 digital inputs
  • Sabre 32-bit DAC
  • Remote and App based control

The Arcam SA20 amplifier is a class G amplifier, toroidal based power supply, acoustically damped chassis, complementary transistor output stages, and exceptionally low levels of distortion and noise. It is capable of reproducing music with all its original authority and detail.

The SA20 houses a Digital-to-Analogue Converter using the reference quality ESS Sabre 9038 DAC, also used inside the Arcam CDS50 CD player/streamer.

The SA20 provides a massive 80 watts per channel into 8 ohms and 176 watts into 4 ohms, allowing for huge extra power reserves from their latest generation class G topology that is both clever and efficient. During normal operation, distortion is measured in less than one part per million so that this massive power is delivered with total control and finesse.
