Description

Mission 778x Integrated Amplifier With Wharfedale Diamond 12.1  Speakers

The diminutive Mission 778x integrated amplifier pays homage to the original 778, launched over 40 years ago. Like its predecessor, the 778x features a compact, half-width design, delivering sound that surpasses its small size. While it shares the original’s versatility with a range of inputs, the internal circuitry has been completely revamped to meet modern standards.

The Mission 778x offers an engaging, detailed, and refined listening experience, excelling in detail, timing, and dynamics, no matter the source or format. Designed for today's audiophile while embracing Mission’s rich heritage, the 778x amplifies your music with vibrant expression and enjoyment.

Vinyl Ready

The built-in phono stage features a JFET-based circuit with precise RIAA equalization, optimized for MM cartridges. This high-quality, low-noise input eliminates the need for an external phono pre-amp, ensuring your vinyl sounds its best.

Versatile Connectivity

As well as Bluetooth for high quality wireless streaming the 778x also features a wide range of digital and analogue source inputs including USB, coaxial digital, 2 x optical inputs and twin RCA analogue inputs. RCA Pre-out allows for future upgrade to a more powerful amp if required.

High-Performance DAC

The 778x doesn’t stop at Bluetooth. It features a top-tier ESS ES9018K2M Reference DAC with ESS Technology’s 32-bit HyperStream architecture and Time Domain Jitter Eliminator. This ensures ultra-low noise and high compatibility with digital audio files, supporting sampling rates up to 384kHz (PCM) and DSD256 for superb sound quality.

Headphone Amplifier

The 778x’s built-in headphone amplifier rivals the performance of standalone headphone amplifiers costing more than this complete system, delivering a dynamic, detailed sound for all types of headphones, ensuring an immersive listening experience.

Wharfedale Diamond 12.1 Speakers

The Wharfedale Diamond 12.1 bookshelf speakers are a standout choice for listeners seeking high-quality sound in a modest footprint. Blending decades of acoustic expertise with modern engineering, the Diamond 12.1 delivers a rich, balanced, and articulate performance—ideal for stereo setups, desktops, or compact home cinema systems.

At the core is Wharfedale’s proprietary 5" Klarity™ mid/bass driver, crafted from a unique polypropylene/mica composite. This material offers the ideal combination of rigidity and internal damping, allowing the driver to respond quickly and cleanly—producing tight, expressive bass and a smooth, natural midrange.

Complementing the low-end is a 1" soft dome tweeter. The magnet system and the front plate have been optimised to provide wide dispersion and improved integration. Together, these drivers are precisely managed by a high-quality crossover network that ensures seamless, coherent sound across the frequency range.

The cabinet is internally braced to reduce vibration and coloration, while the rear-firing circular reflex port enhances bass extension without overwhelming smaller rooms. This makes the Diamond 12.1 flexible in placement—on stands, shelves, or closer to walls.

Finished in a choice of stylish woodgrains or matte white, the Diamond 12.1 pairs modern aesthetics with genuine hi-fi performance.

Package includes a Free 2m pair of QED XT25 Pre-terminated speaker cables worth £79.95. (see below)
