Yamaha’s flagship AV pre-/power amplifier combination from its AVENTAGE range features an 11.2-channel, 4K-compatible processor that offers state-of-the-art connectivity and all the features the serious home theatre fan could want, plus a heavyweight 11 x 150W power amp. The two separates, both of which employ rigid vibration-damped chassis, hook up via balanced XLR or cinch connections. In tandem they are exhilarating and able to enliven even the dullest-sounding speakers. The CX-A5000’s parametric equaliser produces superb room correction, including extensive bass management, with all eleven channels individually assignable to suit a variety of configurations. Meanwhile, the MX-A5000 utilises its discrete amps to deliver astonishing levels of power. Overall, Yamaha’s CX-A5000/MX-A5000 pairing makes a superb choice for a high-end home theatre.
