Product Description

Arcam SA20 integrated stereo amplifier is based on the fantastic earlier A29 model, using proprietary new Class G technology.

Hybrid Amplifier

When deciding on the type of amplifier to use in the SA20, Arcam was faced with two common problems; the traditional class A amplifier uses a single power source, which runs at full capacity, irrespective of the signal. This is great for revealing subtle details in a recording at low levels but are unable to supply extreme levels of power when it is necessary. The Class A/B amplifiers are common amplifier choice, which switches between the two amplifiers, one for each half of the waveform. These are more efficient but suffer from crossover distortion, since the details at low levels can get lost with the mismatch between the two switching over.

A Class G amplifier is a hybrid design, which uses a Class A amplifier for low-level signals, and when required it can provide extra power when it is required.

The SA20 has been rated at 80wpc into 8 ohms, with both channels being driven. The SA20 has less than 20wpc in pure Class A mode, whilst allowing for extra power when it is needed with demanding speakers. This game-changing amplifier is a complete must for music-lovers seeking genuine excellence in an amplifier at a very affordable price point.


As with the SA10, this amplifier is very versatile with five analogue inputs (1x line/MM switchable) and three digital inputs (two SPDIF and one optical). Also, the SA20 comes fully equipped with a top class DAC (ESS Sabre 9038) as has been employed in the irDAC2.


Controlling the SA20 is very simple with the new backlit infra-red remote control, but it can also be controlled with your smartphone it tablet using ARCAM’s IOS app, Musiclife or by RS232.
