The Way To Avoid Errors When Purchasing Amplifiers
by Mike Heller
If you have spent a good deal of money on a pair of good-quality loudspeakers, you want to be certain that you get an amplifier which will provide brilliant audio quality while meeting your budget. I will offer various pointers regarding audio amplifier technologies to aid you make the right purchasing decision.
There is a flood of different audio amplifiers available which all differ in their specifications, shape and size. This makes it hard to decide which model to choose. You don't have to be a specialist. Just follow some straightforward rules and you ought to be pleased with your amplifier.
The most evident parameter is the size of the amplifier. There are models that are as big as half your living room whilst some of the newest mini amplifier types are as tiny as a bar of soap. Numerous models will be the size of a ordinary audio rack so that you can simply stack it on top of your audio equipment. There are a number of core amplifier technologies available. One technology is named "solid-state". Solid-state amplifiers now make up for the bulk of audio amps. In the past, tube amplifiers have been popular. Even today tube amplifiers are still available. Unfortunately, tube amplifiers have fairly high audio distortion which describes how much the audio signal is degraded by the amplifier.
The huge majority of today's audio amplifiers are solid state amplifiers as opposed to more conventional tube amplifiers. Tube amplifiers have been prevalent a decade or so ago. Tube amps, on the other hand, have a relatively high amount of harmonic distortion. Harmonic distortion describes how much the audio signal is degraded while being amplified. This term is often used while comparing the audio quality of amplifiers.
Tube amplifiers will have audio distortion of up to 10%. Solid state amplifiers will have less audio distortion depending on the amplifier technology that is employed. The most conventional amplifiers use a "Class-A" and "Class-AB" technology. These amps are also known as "analog amplifiers". Whereas amplifiers using these technologies generally have low audio distortion, power efficiency is only 10% to 30%. This means that the majority of the electrical power supplied to the amplifier is wasted as heat whereas a small fraction is used to amplify the audio signal.
Your amplifier should deliver enough power to drive your speakers. The amount of power will depend on the power handling rating of your loudspeakers. An additional parameter is the size of your room. Loudspeaker power handling is given as peak power which denotes the maximum amount of power during short bursts while average power refers to how much power the loudspeakers can handle constantly.
If your listening environment is rather small then you might not need to drive your speaker to its rated power handling value. You would most likely be good having an amplifier that can deliver 20 to 50 Watts even though your speakers may be capable to handle 100 Watts of power. Low-impedance loudspeakers typically offer high sensitivity and are easier to drive to high volume than high-impedance loudspeakers. Check your amplifier manual to make sure that your amplifier can drive your speaker impedance.
Lastly, be certain that your amp introduces little noise and has a broad enough frequency response. High-quality amps will have a signal-to-noise ratio of at the very least 100 dB and a frequency response of at least 20 Hz to 20 kHz.
