NES400ES/450D
NES400ES high-quality, high-power monaural amplifier from ESOTERIC
NES450D high-quality stereo amplifier with built-in Over Quality module
The NES400ES was developed in collaboration with ESOTERIC COMPANY, a high-end Japanese audio manufacturer. This monaural power amplifier offers high-end, high-quality sound with professional-grade faithful resolution of original sounds. Utilizing the proven Over Quality Series discrete amplifier, the input stage and dividing stage of the NES450 is capable of 400 W in MONO mode. In addition to stereo specifications, this series also offers bi-amp specifications for use as a driver for large speakers with a marginable low-power range and a mid- to high-power range of 150 W. Both models incorporate a fan-less design in order to ensure maximum quietness.
