Today I share my look at the remarkable $6,320 a pair Atma-Sphere Class D monoblock amplifiers. Measuring a diminutive eleven inches wide, thirteen inches deep, standing just three inches tall, at an unimposing fourteen pounds, you may not be prepared for the surprising level of performance you are about to experience.
The use of GaNFET technology, powered by a linear power supply, using a fully balanced topology, all combine to allow this uncharacteristic solid-state Class D amplifier from Atma-Sphere, to more closely mimic the degree of smoothness and coherence one typically associates with better valve-based amplifiers, thereby satisfying a subset of the design goals.
