About the Class D
The Atma-Sphere Class D is a pair of monoblock Class D power amplifiers designed by Atma-Sphere Music Systems. Featuring proprietary Class D modules with GaNFET output transistors, they deliver the midrange smoothness and high-frequency finesse of excellent tube amps but with significantly lower distortion, lower output impedance, and higher efficiency. Stable with all loads and inputs, low-noise even with horn speakers, and over-current protected. Accepts single-ended and true balanced inputs. Classic Wrinkletex™ finish and three-year warranty. Dimensions per monoblock: 13"D x 11"W x 3"H (33 x 28 x 8 cm), weight 14 lbs (6.35 kg) each.
