Arcam A50 Signature / CD25. | Class G Amplification explained (James Todd, Arcam)

At HIGH END Vienna 2026, we sat down with James Todd from Arcam to discuss the company’s 50th anniversary products: the new A50 Signature integrated amplifier and CD25 reference CD player. The A50 Signature sits at the top of the Radia lineup and is Arcam’s most advanced implementation of its renowned Class G amplification technology. During our conversation, James explains how Class G works, why Arcam has continued to develop it for decades, and how it differs from traditional Class A and Class AB amplifier designs. The A50 Signature is also the first Arcam integrated amplifier to feature a fully dual-mono Class G architecture. We also discuss the new CD25, Arcam’s flagship CD player, featuring a dual-mono DAC architecture and ESS Hyperstream 4 DAC technology.
