Full Description
The Mission 778x Integrated Amplifier offers diverse connectivity options, including digital coaxial and optical inputs, three RCA inputs, and a moving magnet phono input for turntables. As well as physical connections, it supports Bluetooth streaming in aptX and AAC codecs. The 778x features a Class-AB power amplifier design with a 200VA toroidal transformer for strong sound output. It also includes a preamp section and a hi-res onboard DAC with an ES9018K2M chipset, offering a sampling rate of up to 384kHz (PCM) and DSD256.
Accompanying this amplifier, the Monitor Audio Bronze 500 Floorstanding Speakers offer premium audio features that elevate your music. Ceramic-Coated Aluminium Magnesium (C-CAM) drive units are utilised throughout the speakers, from their large eight-inch midbass drivers to the 25mm gold dome tweeter. This strong and ultra-lightweight material is key to the speakers’ sensitivity and responsiveness, along with the performance-enhancing HiVe II bass-reflex rear ports which allow air to move smoothly from the cabinet. A matching magnetic grille is also supplied with each speaker, along with an outrigger feet kit and a choice between floor spikes and rubber pads for stability wherever they’re placed.
To ensure you can set up your new home audio system instantaneously, we’ve included the Fisual Premium Hi-Fi Cable Package. This includes a 10-metre length of speaker cable (enough to split and position your speakers up to five metres from the amp), a pack of easy-to-use screw-on banana plugs, and a stereo phono / RCA cable to connect at least one audio source of your choice, be it a CD player, tuner, or streamer. Order from AV.com and get everything you need for system setup in one neat package.
Please Note
The speaker cable in this bundle is provided as one 10 m length and comes unterminated. Banana plugs are included in the bundle, but are not provided attached and require some short preparation before use.
