Arcam SA20 Integrated Amplifier Overview

From the outside, Arcam’s SA20 integrated amp seems like simplicity itself. The SA20 sports a complete set of analog inputs – including a phono stage for vinyl enthusiasts – an array of optical/coaxial digital inputs, a line-level output to feed an auxiliary amp, and an Ethernet and RS232 connection for home automation integration. But, like every other component designed by high-end UK manufacturer Arcam, it’s engineered inside and out for superior sound. And it’s the least expensive item in the company’s line to feature full Class G amplifier design. Arcam’s unique system uses multiple power supplies to deliver distortion-free audio at the subtlest listening levels as well as dynamics without current constraints. Simple and sublime, the SA20 makes the perfect partner for a moderate listening system, contributing superb sonics and true audiophile credentials.

A higher class of amp

The British audiophile company A&R Cambridge (Arcam for short), founded by two engineering students at Cambridge University in 1976, has been designing high-end audio components in the UK for decades, including pioneering research into amplification circuitry. The company’s research led to the development of its unique Class G amplification system, which eliminates the harsh “crossover notch” distortion that can plague traditional Class AB circuit designs. By using multiple power supplies and instantaneous digital switching, Class G is highly efficient  with vanishingly low distortion, and is more revealing of sonic subtleties with few dynamic power constraints.

A true 80 watts

What all that means is that for much of the SA20’s operating range, you’re likely to be listening in the purest amplifier mode, known as Class A, for lowest distortion. And the multiple power supplies and digital switching mean that the 80 watts – and beyond – are always at the ready. As said in its review and Recommended Award: “It feels very much like those claimed 80 watts are always raring to go and there never feels like there is any shortage of power.”

Perfect for phono

You get five analog inputs (one on the front), plus two coax and one optical digital input, enough for game system, set-top box, CD and DVD, and more. And the switchable phono input in particular, notes, has “no background noise, plenty of gain and a real sense of involvement to the music.”

Simple machine, simple control

The SA20 comes with a full-featured remote, which also handles the company’s CD player. And the Ethernet IP control and RS232 connection makes it simple to integrate with such full-home automation systems as Control4.

Will this give full power to the Magepan LRS speaker? Without any strain at all. Also Maggies are 4ohm so how many watts per channel will I get with 4ohm speaker? Is this a 5 channel or a 7 channel device

  Thanks for your question. Arcams PA240 has power ratings capable of driving Magnepan speakers
