The Mission 778X 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 phono stage is based around a JFET-based circuit with precise RIAA equalization. It’s optimized for MM cartridges and as such, it’s a high-quality, low-noise input that eliminates any need for an additional phono pre-amp. 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!

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!

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.
