Cambridge Audio Topaz SR20

The SR20 completes the Topaz range and becomes the most powerful audio amplifier in the line with 100W/channel. It incorporates certain characteristics that have made the SR10 an amplifier of choice such as class A/B amplification, an aluminum chassis to reduce harmful resonances, and dual speaker outputs.

But the SR20 goes further by adding a high-end Wolfson WM8728 DAC and therefore optical and coaxial digital inputs. The 3 analog inputs are still present, such as the MM phono input for your turntable.

The SR20 thus retains the qualities that have made the SR10 an amplifier of choice in its range, while adding features that make it even more attractive.
