50 Watts of Class A with Ultra-Low Distortion: Arcam PA240 Power Amplifier Plays with Incredible Purity, Efficiency, Clarity, and Dynamics

The measured specifications of the Arcam PA240 two-channel power amplifier tell most of the story: 380 watts per channel into four ohms (225Wpc into eight ohms), a nearly invisible 0.2% of total harmonic distortion at continuous output, a mammoth 110dB signal-to-noise ratio, and a sublime 20Hz–20kHz frequency response confirm this 40-pound component's incredible purity and quiet operation. While numbers aren't always everything, in the case of PA240, they directly translate to absorbing playback that allows your music to emerge with transfixing dynamics, clarity, and smoothness.

PA240's involving sonic performance and off-the-charts efficiency owes to its utilization of Class G amplification, which permits low-level details to come through unimpeded while ensuring the amplifier retains the power it needs during challenging passages. Honed to perfection at Arcam from years of testing and implementation by the company's engineers, the all-analog Class G uses Class A technology exclusively for low-level signals and an additional power supply for larger sections of the audio waveform, an engineering solution that eliminating crossover distortion (caused by Class A/B) and any potential power shortages during extreme swings (suffered by Class A). The result: Nothing at all close to Class D, and truly, the best of both worlds.

Of course, PA240 also comes stacked with kind of audiophile-grade parts befitting its status as a high-end dynamo. Its feature set includes a beefy toroidal transformer, acoustically damped chassis, paralleled transistor output stages, and switchable RCA and balanced XLR inputs. Able to be utilized in stereo, dual mono, or bridged mode (where it delivers an eye-popping 790W), PA240 provides you both flexibility and control. Moreover, its elegantly minimalist aesthetics correlate with its strict focus: That on enhancing your listening experiences for years and years to come.
