Power Amplifiers The amplifier is the energy of the system: it provides the power to the speakers. It is used with a preamplifier or with a source with its own volume control. A power amplifier has only one function: to amplify the signal. It performs better than any other type of device in that regard. There are two-channel models (typical choice) or mono models to buy in pairs for even more power. The latter option allows to bring amplifiers closer to the speakers, an advantage. Depending on preferences, a variety of powers and configurations are possible. Our industry-leading power amplifiers benefit from circuits with topology without global feedback, providing unmatched musicality.
