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.
Phono Ready
The phono stage is based around a JFET-based circuit with precise RIAA equalisation. It’s optimised for MM cartridges and as such, it’s a high-quality, low-noise input that eliminates any need for an additional phono pre-amp.
Complementing the typical RCA line inputs are digital and coax connection options and a built-in Bluetooth receiver with an aptX and AAC codec, meaning the 778X offers CD performance via Bluetooth wireless connection. The convenience of streaming music from smart devices, such as phones, tablets or PCs have never sounded so good!
the Mission 778X does not discriminate when it comes to expression and enjoyment of your music reproduction.
