Arcam’s new rHead headphone amplifier is a true linear Class-A design to ensure there can be absolutely no crossover distortion, since this particular distortion is more audible when listening through headphones than it is when listening to loudspeakers. And because stereo imaging is far more critical when listening to headphones than when listening to speakers, Arcam has used the same ultra-linear analogue resistive ladder device as used in the company’s flagship A49 amplifier to control volume in order to ensure the tracking errors that occur with potentiometer volume controls cannot occur so stereo imaging will be exact irrespective of playback volume level. ‘Extensive care has been taken to optimise the circuit layout including using multiple ultra-low noise power supplies,’ said Nigel Ng, of Advance Audio, which distributes Arcam in Australia. ‘The fact that the signal path is fully direct-coupled signal path makes a huge difference to the sound quality: it sounds amazingly natural, is completely engaging and able to reveal the true character of any music that is played through it.’

Ng told Australian Hi-Fi Magazine that Arcam’s rHead is capable of driving the most demanding headphones, for which both 3.5mm and 6.35mm phone sockets are fitted. On the input side, both RCA and XLR inputs (switchable) are available. Available now, the Arcam rHead retails for $895 (RRP)
