Arcam PA240 Power Amplifier Review: A New Benchmark in Class G Excellence
Arcam PA240 Power Amplifier Review – The Arcam PA240 Power Amplifier represents a landmark in Class G design, meticulously engineered in the UK to deliver 225W per channel with the tonal finesse of Class A. If you’re on the hunt for a powerhouse amp that balances raw output and musicality, read on, or better yet, speak with our team at The Audio Tailor to explore what this UK titan can do for your system.

Cutting-Edge Class G Meets Pure Class A Musicality
The PA240’s hybrid Class G topology is the standout feature here. Under normal operation you get a rock-steady 225W channel into 8Ω (20Hz–20kHz, 0.2% THD) with 50W of pure Class A bias ensuring a seamless musical flow at lower levels. Crank into bridged mode and you’ve got an earth-shaking 790W mono block, ideal for power-hungry speakers or larger rooms. This interplay between Class A warmth and G-mode efficiency delivers extended dynamics without compromise.
Rock-Solid Construction & Integration
The toroidal transformer under the hood guarantees unwavering voltage supply, while the acoustically damped chassis curtails mechanical resonance. Switchable RCA or balanced XLR inputs cater to both consumer and pro-level front ends, and Ethernet plus RS232 control slots the PA240 into any custom installation seamlessly.

Soundstage & Performance
Prepare for an expansive soundstage with razor-sharp transient response, thundering bass control, and a smooth treble that reveals every micro-detail. The low 0.001% distortion (80% power, 8Ω at 1kHz) and 110dB A-weighted S/N ratio yield uncanny depth and resolution, faithfully reproducing your favourite recordings.
