About the MB81 SE
The Icon Audio MB81 SE is a pair of single-ended triode mono-block valve amplifiers built around the Russian GU81 transmitting valve. Icon Audio describes it as a high-power SE design with the sound character of multiple 300B tubes in parallel, intended for medium to very large rooms and low- to medium-efficiency loudspeakers. The design emphasizes pure Class A operation, hand-wired construction, robust power supply and output stages, and a vivid, three-dimensional presentation with strong drive and dynamic capability.
