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 tactile 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: JFET-based phono stage offers precise RIAA equalisation. Optimised for MM cartridges, no extra pre-amp needed. RCA line, digital and coax connections complement Bluetooth receiver with aptX/AAC, providing CD-level audio streaming from smart devices. Convenience and sound quality like never before.

  • HIGH-QUALITY COMPONENTS: That’s not all in terms of digital music facilitation. The 778X is also equipped with a high-performance ESS ES9018K2M Reference chip with ESS Technology’s 32-bit HyperStream architecture and Time Domain Jitter Eliminator.

    In the world of digital music files, this means the 778X offers class-leading, ultra-low noise digital audio file compatibility, with a sampling rate of up to 384kHz (PCM) and DSD256!

  • HEADPHONE STAGE:Equal in performance to standalone headphone amplifiers beyond the price-class of this complete system, the design offers high-speed output signal transition thanks to a high slew rate.

    The result is a dynamic, detailed and engaging performance with all manner of headphone types.

  • ALL ROUND PERFORMANCE:The Mission 778X’s all round performance is engaging, detailed and refined. Detail, timing and dynamics excel, regardless of source or medium.

    Designed for the modern-day music enthusiast with a nod to our heritage,the Mission 778X does not discriminate when it comes to expression and enjoyment of your music reproduction.
