2-Channel Hi-Fi Amps

An amplifier is a device used to amplify, or enlarge, the size of an audio signal before it is sent to a speaker. In a home audio system, you will need a preamplifier, amplifier, and a tuner in order to receive high quality sound from your speaker system. An AV receiver provides the services of all three devices, however it is usually at the expense of quality. Integrated amps are similar to receivers, but they are designed to preserve quality, and may be a better option for those wanting an above average home cinema experience. This selection also includes power amps, which are designed to produce signals for extremely powerful devices, such as large subwoofers and floor standing speakers. Some amplifier models are wireless, connecting through bluetooth or wifi, to reduce the need for cables.
