ARCAM PA720: 7‑channel Class G power amplifier with 140 W per channel

The ARCAM PA720 is a reference‑grade multi‑channel power amplifier for anyone looking to take a home cinema (or multi‑channel audio) system to a more serious level, with greater authority, control and dynamics. With 7 channels of amplification and ARCAM’s Class G architecture, it delivers 140 W per channel (per manufacturer), making it an ideal match for AV processors (e.g., AV41) or AV receivers with pre‑outs when the goal is a clear amplification upgrade.

ARCAM’s Class G is designed to combine efficiency with sound quality, keeping the amplifier comfortable during demanding passages and responsive to transients. In real use, that means more impact with soundtracks, better bass grip and a cleaner presentation when the system is pushed—especially with harder‑to‑drive speakers or larger rooms.

Like other HDA power amps, the PA720 uses best‑in‑class parts: a toroidal‑based power supply, an acoustically damped chassis, paralleled transistor output stages, and a focus on exceptionally low distortion. The aim is to preserve detail and separation while maintaining musicality—something ARCAM is known for bringing from stereo hi‑fi into multi‑channel systems.

If you’re building a 5.1.2/7.1.2/7.1.4 setup and want a robust amplification foundation, the PA720 is a “core” solution that simplifies installation and elevates the final result, especially when paired with room correction (e.g., Dirac Live in the processor/receiver).
