Selecting the perfect type is easier said than done while confronted with a large amount of different technical jargon as well as specs, for example "T-amp", "channel separation", "efficiency" etc. You might not even fully be aware of the most simple of these terms, for example "amplifier power". I will describe the term "amplifier power" a bit more in this piece of writing. "Output power" is one of the most basic terms describing amplifier performance. Then again, it is often misunderstood. Some companies also in history have used this term in a perplexing manner to hide the real performance. Amplifier specifications are at times awkward to understand since they are not fully standardized. Therefore it can be difficult to figure out the actual performance of the amplifier only by focusing on the specs. One decent approach however is to do a listening test prior to paying for your power amplifier. Throughout this test you ideally wish to install the amp in a comparable setting as your use. Next I am going to describe the "output power" rating of power amps. This rating is one of the most fundamental and maybe significant specifications to understand.
Several of the terms which amp producers make public regularly are deceptive and do not necessarily give a good indication of the actual performance of the amplifier. Now I will explain the "wattage" spec of power amps. This term is one of the most basic and possibly essential specs to comprehend. "Output power" describes how loud your amplifier may drive your speakers. Depending on your application, you may go with a small amp delivering just several watts or a larger one offering several hundred watts. Most home stereos only incorporate amplifiers that have several watts power which typically is adequate for a small space. If you plan to shake your walls then you clearly want to opt for an amp that has as much as a few hundred watts. For superior music quality, you may want to go with an amp which has bigger output power than you require because most amps will exhibit rising distortion as the audio output power increases.
Several specifications will provide the wattage in "Watts peak" while others are going to display "Watts rms". "Peak" means that the amplifier is able to provide the power for a brief period of time only whilst "Watts rms" means that the amplifier will constantly deliver that level of power. The peak spec has been somewhat abused by vendors showing huge peak audio power while their amplifiers are actually constructed with tiny power supplies unable to handle more than only several watts rms power.
Nowadays most amplifiers are going to state rms power which provides a better indication of the amp's real performance. Though, please make sure that your amplifier has adequate headroom to stay away from clipping of the audio. Having sufficient headroom is vital as music signals differ a lot from sine wave signals that are used to quantify rms power. Brief bursts of large power are repeatedly found in audio signals. These peaks will drive the amp into high distortion unless the peak power is big enough.
Please notice that often the peak power of the amplifier is going to depend upon the impedance of your loudspeakers which is usually between 4 and 8 Ohms. Because of the limited amplifier supply voltage, the largest output wattage will be half if you attach an 8-Ohm loudspeaker of the peak power that the amplifier may output to a 4-Ohm loudspeaker. As a consequence often largest output power is shown for a particular speaker impedance.
