The new 778X integrated amplifier is a nod to Mission's original 778 launched way back in 1983. The new 778X has much in common with the original, a compact, half-width design that delivers a sound that belies its diminutive footprint. Like the original the Mission 778x sports a useful range of inputs, its circuitry has been entirely redesigned to meet and exceed contemporary standards, the new amp is a great sonic match for Mission’s current range, just as the 778 was in its day. 

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.

The Mission 778X integrated stereo amplifier is available now in a choice of silver or black.

Perfect for Turntables

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.

Bluetooth wireless connection

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!

High-performance DAC

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 amplifier

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.


Mission also has a choice of two complete systems that combine the 778X with popular standmount models from the Mission range of speakers, forming great-value, high-quality audio systems. The first includes a pair of Mission LX-2 MkII speakers at a package price of £649, saving £130 from the individual RRPs. The second upgrades the speakers to the Mission QX-2 MkII at a package price of £799, saving a total of £150. In both cases, the speakers are available in a choice of matt black, matt white or walnut.
