What's in the Box
- Mission 778X integrated amplifier
- Remote control
- Power cable
- User manual and documentation
Overview
The Mission 778X is the beating heart of the Mission 778 system, an integrated amplifier that revisits the spirit of the classic Mission 778 while adding modern digital capability. Built with Audiolab electronic engineering under the same IAG group, it pairs a clean, quietly powerful amplifier stage with a genuinely capable digital front end so a single box can serve as the hub of a complete music system.
Inside sits an ESS Sabre32 ES9018K2M DAC handling PCM to 384kHz over USB and DSD up to DSD256, feeding an amplifier rated at 2 x 45W into 8 ohms and 2 x 65W into 4 ohms. A wide input set covers coaxial, two optical, PC USB, two AUX RCA and Bluetooth 5.0 with aptX and AAC, while a moving magnet phono stage welcomes a turntable and a headphone amplifier drives loads from 20 to 600 ohms. Very low distortion below 0.005 percent and a signal to noise ratio above 108dB reflect the careful engineering behind it.
It is designed for the listener who wants one tidy, well made component to anchor a room, whether that is a pair of classic Mission stand mounts, a streamer, a CD transport or a record player. The compact chassis and choice of black or silver finish make it easy to place, and an RCA pre-out leaves the door open for future expansion.

How the 778X Compares
Mission 778X vs Audiolab 6000A MKII
Both share IAG electronic engineering DNA, so they aim for the same clean, low distortion character. The Audiolab 6000A MKII presents that engineering in Audiolab's own system context, while the 778X is styled and voiced as the hub of the Mission 778 family. Choose the 778X if you want it to anchor a Mission speaker and source system with a coherent look and feel. See the Audiolab 6000A MKII.
Mission 778X vs LEAK Stereo 130
The LEAK Stereo 130 leans into a retro aesthetic with wood side panels and a warm, vintage inspired presentation, also built within IAG. The 778X takes a more contemporary, understated approach as part of the Mission 778 system. Pick the 778X when a modern minimalist chassis and Mission system synergy suit the room. See the LEAK Stereo 130.
Mission 778X vs Yamaha A-S801
The Yamaha A-S801 offers more amplifier power and Yamaha's long standing house sound with a familiar tone control set. The Mission 778X focuses on a compact footprint and being the tidy digital heart of a matching Mission stack. Choose based on whether you prioritize higher rated wattage or a purpose built Mission system centerpiece. See the Yamaha A-S801.
Recommended Speakers and Source
The 778X is designed to anchor a Mission system, so its natural partners are the classic Mission stand mounts and a matching 778 source.
- Mission 770 Classic A faithful reissue of the legendary 1980 Mission 770 with polypropylene mid-bass driver and real wood veneer, making it the flagship stand mount partner for the 778X.
- Mission 700 A classic series stand mount with the signature Mission character, an easy and satisfying match for the 778X in a mid sized room.
- Mission 750 A compact classic series bookshelf speaker that pairs neatly with the 778X for smaller spaces and near field listening.
- Mission 778S Streamer The matching network music streamer feeds the 778X built-in DAC over a digital connection to complete the streaming side of the 778 system.
- Mission 778CDT CD Transport A dedicated CD transport with no built-in DAC, it relies on the 778X ESS Sabre DAC for conversion, forming a clean disc based front end.
