Arcam’s A49 integrated, C49 pre-amplifier and P49 power amplifier represents the pinnacle of Arcam’s stereo audio engineering. We set out to incorporate everything we have learnt in almost 40 years to deliver an amplifier that will set new standards and provide class leading sound quality for the best possible reproduction of your music. Drawing on the many years of amplifier design experience at Arcam, all three products use the best quality components and engineering practice to produce a product that will give many years of musical pleasure and reliable service.

With a class G amplifier, toroidal based power supply, acoustically damped chassis, paralleled transistor output stages and exceptionally low levels of distortion and noise both the A49 and P49 are capable of reproducing music with all its original authority and detail. Both the A49 and C49 feature dual mono volume controls and a balanced signal path all the way though the product together with distortion nulling input multiplexers. Rest assured you will be hearing the music just as the artist intended. Both the A49 & P49 have been designed to leapfrog the competition with a massive 200 watts per channel into 8 ohms and 400 into 4 ohms. It delivers 50 watts in pure class A mode while allowing for huge extra power reserves from our latest generation class G topology that is both clever and efficient. Distortion is measured in less than one part per million so that this massive power is deliver with total control and finesse.

There have been great strides made in improving audio sources and loudspeakers in recent years and the time is right to match them in the field of amplifier design. These ground breaking amplifiers are must audition amplifiers for music lovers who understand that power is nothing without control. The P49 has been designed with system building flexibility in mind and can be configured as a traditional stereo power amp, bridged mode or dual mono mode allowing for the “ultimate” system of a C49 with six bridged P49s tri-amping the speakers.
