When you have spent a good deal of money on a pair of good-quality speakers, you want to be certain that you will get a good amplifier that delivers excellent audio quality while meeting your allowance. I’ll give some pointers about audio amplifier technologies that will help you make the right buying decision.
Audio amplifiers are available in many different size and shapes. They will use different technologies and still have many technical specs. This will make it tough to pick which model to pick out. You won’t need to be a specialist. Just follow some simple guidelines and you should accept your amp.
An important criterion may be the size the amplifier. You can purchase models which can fill half a space. In comparison, a few of the latest miniature amplifier models are no larger than decking of cards. Many units would be the height and width of a typical audio rack to enable you to easily stack it on top of your audio equipment.
Nearly all today’s audio amplifiers are solid state amplifiers instead of some tube amplifiers. Tube amplifiers have been dominant 10 years or so ago. However, tube amplifiers have fairly high audio distortion. Audio distortion identifies the amount the audio signal will be degraded while passing through the amplifier which is shown in percent. This value is often used when you compare the audio quality of amplifiers.
Tube amps will have audio distortion of up to 10%. Solid state amplifiers will have lower audio distortion with respect to the amplifier technology that is used. Probably the most traditional amps make use of a "Class-A" and "Class-AB" technology. These amplifiers are also called "analog amplifiers". This technology offers fairly low audio distortion. However, the ability efficiency is only 10 to 30%. Which means that almost all of the electrical power supplied on the amplifier is wasted as heat while a tiny fraction is used to amplify the audio signal.
In comparison, "Class-D" amplifiers which are also known as "digital amplifiers" offer a power efficiency of typically 80 to 90%. This enables the amplifier and power source to be made much smaller than analog amplifiers. The potential downside is that digital amplifiers will have higher audio distortion than analog amplifiers. Chiefly a result of the switching distortion of the output power stage. Most recent digital audio amplifiers, however, require a feedback mechanism and can minimize the audio distortion to below 0.05%.
When selecting an amplifier, ensure that the output power is sufficient drive your speakers. The necessary power is decided since much power your speakers are equipped for as well as the size of a room where you will probably be listening. Speaker power handling capability emerges as peak power and average power. The height power value refers to simply how much power the speaker are equipped for for a while of energy as the average power handling value describes how much power you’ll be able to drive the speaker at continuously without damage.
