Solid State Power Amplifier Mission 778X
Over the past 45 years, Mission has become famed for loudspeakers that break the norms of price-point, technology and design. Yet, in its illustrious history, Mission was also responsible for some equally prolific hi-fi electronics.

Thus, the Mission 778X is a revisit of a classic Mission amplifier concept that was the Mission 778 – an affordable integrated amplifier that offered simplicity in operation but over-performed in the driving of loudspeakers.
Today’s Mission 778X maintains the influence of simplistic operation, large tractile controls, and a multitude of inputs. It’s a compact, ’80s inspired integrated amplifier that is fully equipped to meet the demands of modern music lovers, from vinyl fans to digital streamers. Modern twists, such as LED level indicators and all-encompassing connectivity options, make the 778X a truly contemporary integrated amplifier. Boasting a genuine 65 watts (@4 ohms) of power via an utterly modern and refined signal path, to standards akin to the exemplary standards to which Mission loudspeakers are developed.
