Arcam SA20 Class G Integrated Amplifier
There are two frequent problems with hi-fi amplifiers. Class
A, the traditional audiophile’s choice, uses a single power supply constantly
running at full capacity, even when there’s no signal coming through. Great for
reproducing those subtle details at low levels however struggles to provide
extreme power when needed.
Class A/B, the most common amp class, switches between the
two internal amplifiers, one for each half of the waveform. Far more efficient
but often a recipe for crossover distortion, since those low-level details we
crave can get lost within any mis-match between the two switching over.
Class G is essentially a hybrid amplifier, utilising Class A
specifically for low-level signals, but when required switching in an
additional power supply to power those larger sections of the waveform.
