If you want to create a surround or home cinema setup, the base is a surround sound receiver. This can control 5, 7, or 9 speakers. Combine this with 1 or 2 subwoofers and you get the optimal cinema experience at home. Is this not for you? Think of a stereo receiver with an optional amplifier. This way ,you can enjoy stereo sound at home. If you want to listen to wireless streaming services such as Spotify Connect, AirPlay, and Google Cast, choose a receiver with WiFi.
