The mighty AMS50 follows the AMS35p and precedes the AMS100 in the trio of exceptional power amplifiers within our AMS range. Each amp features the same core Class A excellence, but packaged at different levels of size, power and price. This means you can pick the power amp that best suits your specific speakers, room and budget, while knowing you’re buying the premium performance at every point.

As its name suggests, the AMS50 offers 50 Watts per channel into 8 Ohms, though this doubles to 100 Watts per channel into the 4 Ohm impedance of many modern speaker designs.

The AMS50 is the perfect partner for our Primo pre-amp, sharing the same state-of-the-art engineering and premium aesthetics.

As Noel Keywood enthused in his Hi-Fi World review: “The big AMS50 has an array of qualities that mark it out as an utterly superb amplifier no matter what loudspeaker it is paired with”. He concludes: “it is probably the best solid-state amplifier I have ever heard”.
