The Best Place To Find A Great Bargain On Audio Amps

I will have a look at several audio amplifiers and describe some essential language to help you choose the perfect amplifier for your speakers Audio amplifiers are available in all different shapes and sizes. They utilize different technologies and have numerous technical specs. However, you don’t have to be a guru to select the perfect model. This permits them to be stacked on top of your other audio equipment. The vast majority of todays audio amps are solid state mini amplifiers vs more traditional tube amps. Tube amps have been prevalent a decade or so ago. Unfortunately, tube amps have fairly high audio distortion which describes how much the audio signal is degraded by the amplifier.

Several of the most popular technologies in the past have been “Class-A” and “Class-AB” technologies. Amps based on any of these technologies are also called “analog amplifiers”. Power efficiency describes how much of the electrical power is utilized to amplify the audio versus being wasted as heat. “Class-D” amplifiers, however, which are also known as “digital amplifiers” have a power efficiency of no less than 80% and are smaller and have a smaller power supply than comparable analog amplifiers. The tradeoff is that digital amps frequently have larger audio distortion than analog amplifiers. This is for the most part a result of the switching distortion of the output power stage. The peak value indicates how much power the loudspeaker can tolerate for small periods of time. The average value on the other hand describes how much power the loudspeaker can handle constantly without harm. If you have a rather small listening area then 20 to 50 Watts of power should be sufficient although your loudspeaker might be rated for 100 Watts or higher. Typically a low-impedance loudspeaker will be simpler to drive to high volume than a high-impedance loudspeaker. Check your amplifier manual to ensure that your amplifier can drive your speaker impedance. Signal-to-noise ratio describes how much noise the amp will generate and should be no less than 100 dB for a high-quality amp.
