A receiver provides the services of an amplifier
, preamplifier, and tuner in a single device. They are popular for this convenience, however they generally produce lower quality sound compared to using separate devices. This selection of home theatre receivers is geared towards high quality amplification suited for a hifi speaker system
. One Onkyo package even includes a power amplifier in order to provide top-notch amplification in the simplest way.
One drawback of an AV receiver is the lack of control over each step in the amplification process. If you have separate devices, you have the ability to replace only the preamplifier
or only the tuner, rather than purchasing an entirely new receiver. However, the simplicity of a single device is extremely efficient and suitable for most home audio systems.
