The Parasound Halo A21+ is a high-end 2-channel stereo power amplifier designed for listeners who demand substantial power, exceptional current delivery and refined musical performance. Its high-bias Class A/AB topology provides smooth and detailed reproduction while maintaining the power reserves necessary for demanding loudspeakers.

The A21+ delivers 300W per channel into 8Ω and 500W per channel into 4Ω, with both channels driven across the full 20Hz–20kHz audio range. Its 60A peak current capability per channel provides excellent control over difficult speaker loads and demanding musical transients.

A large 1.2kVA shielded toroidal transformer and 108,000µF of filter capacitance provide a robust power supply with substantial energy storage. The amplifier uses a high-current output stage with carefully matched components for low distortion and excellent linearity.

Balanced XLR and unbalanced RCA inputs provide flexible connectivity to high-end preamplifiers, DACs and AV processors. A direct-coupled signal path helps maintain a clean and accurate signal, while gold-plated 5-way speaker binding posts provide secure loudspeaker connections.

The A21+ includes both 12V trigger and audio-sensing automatic turn-on, allowing convenient integration into modern home-theatre and custom-installation systems. DC servo and relay protection circuits help protect the amplifier and connected speakers.

With its high-current Class A/AB design, powerful dual-channel output, substantial toroidal power supply and flexible connectivity, the Parasound Halo A21+ is an excellent choice for premium two-channel stereo listening and high-performance home theatre.
