Musical Fidelity - M6s500i - Dual Mono Integrated amplifier - Pre Loved
The M6s500i from Musical Fidelity is a high-end “super-integrated” amplifier designed for the most demanding stereo systems. Internally it employs separate monobloc power-amplifiers—one for each channel—paired with a precision preamplifier section, all enclosed in a robust, heavy chassis. With a rated output of 500 watts per channel into 8 ohms, it offers enormous current reserve and load-driving ability, making it capable of handling almost any loudspeaker with real authority. The sonic character is described as effortless, refined yet powerful, with superb control, dynamic impact and clarity. Built to impress both technically and constructively, it is aimed at serious audiophiles who want “separates-level” performance in a single box.
This amp is supplied with a 6 month warranty.
No box is supplied so pick up is essential.Â
