It was way back in the mid-1970s when Doug Brady showcased the first amplifier from A&R Cambridge (as the company was then known) — the A60, which featured in many of our magazine adverts. The Arcam A25 continued that legacy with great success, earning a reputation for performance and reliability. Naturally, expectations are high for its successor, the Arcam A25+, which is set to carry the torch forward.
