Questyle CMA400i

Questyle CMA 400i, inheriting the state-of-the-art technology of Questyle Golden Reference System, is visually impressive and mysterious for its black and sandblasted chassis, and the amber light of LED indicators. CMA400i can be placed straight with a specially designed stand. Built with four groups of pure Class A Current Mode amplifiers and all discrete circuit, CMA 400i achieves the ultra-low distortion level of 0.0006% and ultra-wide bandwidth up to DC-600kHz(+0,-3dB). The impressive technical performance together with warm and powerful sound makes CMA400i comparable with a high-end headphone amplifier.
