The ideal amp for all your music
With a heritage that stretches back to 1976, Arcam’s amplifiers have always been amongst the best in their class for balancing sound with features.
It was way back in the mid 1970s when Doug Brady showcased the first amplifier from Arcam (A&R Cambridge as the company was called then) the A60 which featured in many of our magazine adverts.
