AN AMPLIFIER

If you’re buying an unpowered surround sound system, you’ll need a home cinema amp to fuel those speakers. We’d go for Denon’s AVR-X2300W (£349, denon.co.uk).

A STREAMER

The Nvidia Shield TV (£190, nvidia.co.uk) offers 4K streaming from your favourite apps while also being able to cast 4K HDR games such as Mass Effect Andromeda from your PC.
