Overview

Delivering 65 watts per channel at 4 Ohms, this compact integrated amplifier features an ESS Sabre32 DAC, Bluetooth 5.0, and an MM phono stage. Supporting 384kHz PCM and DSD256, it brings versatile connectivity to any high performance sound system setup.

The Mission 778X integrates a high performance stereo power amplifier, preamplifier, and digital to analog converter into a compact 236 mm chassis. Delivering 45 watts per channel into 8 Ohms or 65 watts per channel into 4 Ohms, this unit features large tactile controls and LED level indicators. The integrated preamplifier includes two auxiliary line inputs alongside a dedicated JFET based Moving Magnet phono stage with precise RIAA equalization, eliminating the need for an external phono preamp when connecting turntables.

Digital processing utilizes an ESS Sabre32 ES9018K2M Reference chip with 32 bit HyperStream architecture and Time Domain Jitter Eliminator. Digital connection options include one coaxial input, two Toslink optical inputs, a PC USB port, and Bluetooth 5.0 supporting aptX and AAC codecs. The USB interface processes PCM audio files up to 384kHz and DSD up to DSD256, while optical and coaxial inputs support sampling rates up to 192kHz.

Output routing options include coaxial and optical digital outputs, a stereo preamplifier RCA output, and binding posts for stereo speakers. An onboard headphone amplifier with a high slew rate provides dedicated output for headphones with load impedances between 20 and 600 Ohms. Weighing 6.3 kg, this versatile amplifier serves as a central hub for modern smart home integration and multi source sound system setup configurations.
