The Mission 778X integrated amplifier is a nod to Mission's original 778 launched way back in 1983. The 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.

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 778S

The Mission 778S is Mission’s first wireless music streamer, created as the ideal digital companion to the acclaimed 778X integrated amplifier. Designed for modern music lovers, it delivers seamless, high-quality streaming through intuitive app control, flexible connectivity, and audiophile-grade engineering. All of this is presented in the same elegant, compact half-width chassis and striking retro-inspired design that has already made the 778X a modern classic. Together, they form a complete, future-ready system that reflects Mission’s long-standing commitment to musical purity and performance.

The 778 Series Philosophy

The launch of the 778X marked Mission’s return to integrated amplification after more than thirty years, setting a new standard for compact, high-value hi-fi electronics. The 778S now completes the picture, bringing contemporary streaming capability while preserving the same musical priorities, visual harmony, and meticulous attention to engineering detail. Designed specifically for 778X owners and modern hi-fi systems, the 778S becomes the streaming heart of the setup. In keeping with Mission’s heritage, the 778 series blends refined design, exceptional sound quality, and outstanding value with a nod to classic aesthetics and forward-thinking performance.

Streaming Platform And Control

At the core of the 778S lies a robust streaming platform developed in collaboration with Silent Angel, specialists in high-end digital audio streaming. Beneath the distinctive Mission styling, a custom implementation of the Silent Angel streaming engine—carefully optimised by Mission engineers—ensures excellent fidelity, rock-solid stability, and impressive versatility. Accessing music is effortless via the Mission 778S app, offering direct streaming from Spotify Connect, TIDAL Connect, Qobuz Connect, TuneIn Radio, DLNA, AirPlay 2, and USB storage devices. For advanced users, full Roon Ready certification guarantees bit-perfect playback and seamless integration over Wi-Fi or Ethernet, with simple and straightforward setup.

Engineering And Performance

The 778S is built around the ESS Technology ES9038Q2M Reference DAC, featuring 32-bit HyperStream architecture and Time Domain Jitter Eliminator technology for ultra-low noise and exceptional signal integrity. Incoming audio is precision upsampled to 352.8kHz or 384kHz, pushing digital artefacts beyond the audible range and allowing the DAC to perform at its optimal linear point. This approach results in cleaner transients, enhanced dynamics, and a more natural, spacious soundstage. Users can also bypass the upsampling and select from five DAC reconstruction filters, allowing subtle sonic tailoring to suit personal preference and varying source quality.

Connectivity & Flexibility

To accommodate a wide variety of systems, the 778S offers both digital outputs—including USB Audio, coaxial and optical—and high-quality analogue connections. Balanced XLR outputs enable full-resolution playback of high-definition formats such as DSD, while reducing noise and interference for longer cable runs. The onboard headphone amplifier further extends the unit’s versatility, delivering clarity and control across a wide range of headphones, from everyday models to reference-grade designs. As with all Mission products, the specifications are merely the foundation; the ultimate aim remains lifelike musical reproduction.

Music leads, and technology follows.
