If you have spent a good deal of money on a pair of good-quality speakers, you wish to be certain that you get an amplifier which will deliver brilliant sound quality while meeting your budget. I will offer a number of tips on the subject of audio amp devices to assist you make the right purchasing decision.
It is tricky to choose the best audio amplifier as a consequence of the large amount of models. All of these types have different specs. They are based on different technologies and come in all kinds of shapes and sizes. This makes it tricky to make a decision which type to pick. You don't have to be a guru. Just follow some straightforward guidelines and you should be satisfied with your amp.
The huge majority of today's audio amps are solid state amplifiers as opposed to more traditional tube amps. Tube amps have been prevalent a decade or so ago. Unfortunately, tube amplifiers have quite high audio distortion which describes how much the audio signal is degraded by the amp.
There are some core amplifier technologies available. One technology is known as "solid-state". Solid-state amps now make up for the bulk of audio amps. In the past, tube amps have been popular. Even today tube amplifiers are still obtainable. Unfortunately, tube amps have relatively large audio distortion which describes how much the audio signal is degraded by the amplifier.
An audio distortion of up to 10% is typical for tube amps while solid-state amps have lower audio distortion depending on the specific technology. The most traditional amps use a "Class-A" and "Class-AB" technology. These amplifiers are also called "analog amplifiers". Audio amps which are based on these technologies typically have low harmonic distortion. In addition, this technology is quite economical. Though, the drawback is that the power efficiency is only in the order of 20% to 30%. This means that the majority of the electrical power supplied to the amplifier is wasted as heat whereas a tiny fraction is utilized to amplify the audio signal.
In contrast, "Class-D" amplifiers which are also called "digital amplifiers" have a power efficiency of normally 80 to 90%. This allows the amp and power supply to be made a good deal smaller than analog amplifiers. The tradeoff is that digital amps regularly have higher audio distortion than analog amplifiers. This is mostly a consequence of the switching distortion of the output power stage. Newest digital audio amplifiers, though, make use of a feedback mechanism and can reduce the audio distortion to below 0.05%. When selecting an amp, make certain that the output power is sufficient to drive your speakers. The needed power will be determined by how much power your loudspeakers can tolerate as well as the size of your room where you will be listening. There are two values for speaker power handling: peak and average power handling. The peak value indicates how much power the loudspeaker can handle for short periods of time. The average value on the other hand denotes how much power the loudspeaker can tolerate constantly without damage.
In a small listening area, you might not require to drive your loudspeakers to their rated value. 20 to 40 Watts of power will most likely be sufficient. Low-impedance speakers normally offer high sensitivity and are less difficult to drive to high volume than high-impedance loudspeakers. Be sure that your amp can drive your speaker impedance. You can without problems find the rated speaker impedance range in your amplifier's user manual.
Finally, make certain that your amp introduces little noise and has a broad enough frequency response. High-quality amplifiers will have a signal-to-noise ratio of at the very least 100 dB and a frequency response of a minimum of 20 Hz to 20 kHz.
