Home Amplifiers & Preamps

Every time you listen to music on a car radio, a speaker system or a set of headphones, you are benefiting from some form of amplification. Audio travels via a relatively weak signal. So, the signal from a turntable, microphone or audio receiver must first be raised to a standard level with a preamp. Then, a power amp increases the strength of the signal enough to move speaker cones and achieve volume and clarity. Amplifiers can be incorporated within a speaker or audio device, or you can connect a devoted amplifier to your home audio system.

For the greatest control over the quality of your sound system, choose both a preamp and power amp. You will be able to fine-tune your settings for the perfect listening experience. If you want both steps in one device, an integrated amplifier combines the preamp and power amp units. If you are choosing a home theater amplifier, you may enjoy the quality of a premium home audio amplifier.

When it comes to the nitty-gritty details of amplifier types, there are classes of amplifier. Class A amplifiers are rarely used now because they are large and heavy, but audiophiles appreciate their smooth sound quality. Class AB amplifiers are popular choices because they are efficient and can deliver power in a compact, budget-friendly package. A Class G amplifier enhances the AB design in terms of efficiency to reduce size and heat, while the most efficient option is the Class D amplifier.

When putting together the best audio system for your home, you need to pay attention to your speaker and amplifier compatibility. The best amp for home speakers will match your speakers’ capabilities. The impedance rating (in ohms) on your speaker should work with your amplifier specs. A mismatch can lead to overheating and sound distortion. You should also pay attention to compatibility if choosing among car audio amps.
