The M500 features a discrete design with a Class A input stage with matched impedance. The result is a product with minimized signal reflections, input noise and distortion, as well as maximum power transmission and dynamic range in a zero negative feedback design. With special low-noise, high-current toroidal transformers and a robust high-current output buffer, the M500 delivers transparent, holographic, fatigue-free sound. All components have been carefully selected for their sound characteristics and durability, which ensures that your amplifier will last a long time.
