Arcam SA20

Discontinued replaced by Arcam A15

The SA20 integrated amplifier uses Arcam’s proprietary Class G technology.

It is the replacement for the previous A29 amplifier, at a lower price AND with digital inputs

The SA20 is rated at 80wpc into 8 ohms (both channels driven).

It delivers just under 20wpc in pure Class A, while allowing for huge extra power reserves for the most demanding of loudspeakers.

As with the SA10 this amplifier has 5x analogue inputs (1x line/MM switchable) but the 3x digital inputs (2x SPDIF and 1x optical) are supplied by the ESS Sabre 9038 reference DAC (as employed in the irDAC2).

The SA20 also comes with a brand new learning backlit infra-red handset and can be controlled over IP by ARCAM’s IOS app, Musiclife or by RS232.

A perfect partner to the Arcam CDS50 CD player.

Additional information




Arcam Arcam been developing and making CD players for almost 30 years, and for 40 years the descendants of the amplifier with which the company started in consumer electronics, and as far back as 1995 expanded into home cinema electronics, developing a world-class reputation for making some of the best-sounding AV electronics


In home cinema they have also developed their own DVD players and, more recently, Blu-ray players from scratch here in the UK, engineering them using  decades of experience in CD players to ensure they play music as well as they do movies, delivering better all-round performance than other brands' products. Hard-won techniques for preserving and handling the most delicate signal and reproducing music with all its subtleties, nuances and excitement intact are now in our blood. We know that as audio moves on from CD to even higher definition formats, we're determined our products should continue to serve the music faithfully and deliver maximum enjoyment to the listener.
