Quad Artera amplifiers represent one of the best hifi bargains around. With their roots in the amazing 405, the circuit has been refined for improved sound-quality.
With a large transformer and space for larger power smoothing capacitors it is a robust sounding candidate for upgrade.
With our upgrades applied, the Quad Artera gets smoother, slightly more detailed and has more air & space around instruments. The improved and additional capacitors remove more noise and ripple from the power rails improving every aspect of the sound. You get greater transparency and a cleaner sound which keeps you listening for long periods with no listening fatigue.
