Arcam SA20 2x90w Amplifier
The SA20 is a Class G hybrid amplifier, utilising Class A for low-level signals, then adding an additional power supply to power those larger sections of the waveform. GB Delivery 2-3 Days
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.

Frequently Asked Questions and Answers
What is the difference between an Integrated Amplifier, Pre-Amplifier & Power Amplifier?
An amplifier has 2 main internal sections. The switching & control section is called the Pre-Amplifier, this allows you to select your source & volume & sometimes allows tonal adjustment. The Power Amplifier then takes the signal from the Pre-Amplifier & amplifies it to power your speakers. An Integrated amplifier has both the Pre-Amplifier & Power Amplifier combined into a single box.
