How You Can Stay Clear Of Mistakes While Buying Stereo Amps
By Mike Heller
If you have paid a good amount of money on a pair of good-quality loudspeakers, you wish to be sure that you get an amplifier which will provide excellent audio quality while meeting your budget. I will offer various pointers about audio amp devices to assist you make the best buying decision.
Amplifiers vary in their size and range from types that will take up a good part of your living room whilst a number of of the latest mini amplifier types are as tiny as a deck of cards. Various amplifiers are rack sized. This enables them to be stacked on top of your other audio equipment.
A vital parameter is the size of the amp. You can get models that can fill half a room. In contrast, some of the most recent miniature amp models are no bigger than a deck of cards. A lot of amps are rack sized. This permits them to be stacked on top of your other audio equipment.
The largest part of modern audio amps are based on solid-state technology while a tiny portion is based on tube technology which has been popular over a decade ago. Regrettably, tube amps have relatively large audio distortion which describes how much the audio signal is degraded by the amp.
In comparison, "Class-D" amps which are also named "digital amplifiers" offer a power efficiency of generally 80 to 90%. This allows the amp and power supply to be made a great deal smaller than analog amplifiers. As a result of the switching output stage, digital amplifiers normally have larger harmonic distortion than analog amplifiers. Though, a few of the most recent models are capable to reduce distortion to 0.05% and lower by employing a feedback mechanism.
When choosing an amp, ensure that the output power is enough to drive your loudspeakers. The required power will be determined by how much power your speakers can tolerate as well as the size of your room where you will be listening. Loudspeaker power handling is given as peak power which denotes the greatest amount of power during short bursts whereas average power refers to how much power the speakers can handle continuously.
If you have a rather small listening environment then 20 to 50 Watts of power should be enough even though your speaker might be rated for 100 Watts or higher. Low-impedance speakers typically offer high sensitivity and are less difficult to drive to high volume than high-impedance speakers. Not all amps can drive any speaker impedance. Find out the impedance of your loudspeaker which is given in Ohms. Then look at your amplifier manual to make sure that your amplifier can drive this impedance.
Other key parameters are the signal-to-noise ratio and frequency response which should be in the order of at least 100 dB signal-to-noise ratio and 20 Hz to 20 kHz frequency response for high-quality amps.
