Choosing the ideal model is tricky while faced with a huge amount of different terms plus specifications, like "T-amp", "channel separation", "efficiency" et cetera. You may not even fully be aware of the most basic of these terms, for example "amplifier wattage". I will describe the term "amplifier wattage" a bit more in this article. "Wattage" is one of the most essential terms describing amplifier functioning. Nevertheless, it is time and again misunderstood. A few makers also in history have used this term in a perplexing way in order to hide the real performance.
Some of the terms which amplifier producers make public often are confusing and do not inevitably offer a decent indication of the actual performance of the amp. Now I will clarify the "wattage" spec of audio amps. This spec is one of the most basic and perhaps vital specs to understand. "Power" describes how loud your amplifier may drive your speakers. You want to select the audio amplifier wattage depending on how big your listening space is. Please note that a lot of amplifiers will start distorting the music as soon as the audio reaches bigger wattage. If you want to enjoy low-distortion music then you may wish to select an amplifier which is going to offer you more wattage than you will really require.
There are 2 widespread ways to show amplifier wattage. These are "peak power" and "rms power". "Peak power" describes how much power the amp may offer to your loudspeakers for a quick burst. On the other hand, "rms power" describes how much power the amp can deliver for a prolonged amount of time without being damaged. The peak rating has been somewhat abused by manufacturers showing excessive peak audio power whilst their amps are in reality developed with very small power supplies unable to handle more than only a few watts rms power.
Power is either given as "Watts peak" which means the amp can create brief bursts of this amount of power or "Watts rms" which describes how much power the amplifier may provide for a longer amount of time. The peak specification has been to some extent misused by vendors stating enormous peak audio wattage while their amplifiers are in fact developed with small power supplies unable to handle more than merely several watts rms power. Music and voice is not constant by way of volume. As such the peak power rating is nonetheless essential, although not as significant as the rms power rating. Ideally the amplifier will display both the rms and peak power rating. Having a high peak power rating will ensure enough headroom for music peaks that are widespread in audio signals. The most important reason is that music signals are going to have brief bursts of high power that the amp has to handle. Rms power is measured with a uniform sine signal that hardly compares with a music signal in terms of the power envelope.
On the other hand, be conscious of the fact that the maximum output power also will depend on which type of loudspeakers you are using, specifically the impedance of the loudspeakers. Speakers typically have impedances between 4 and 8 Ohms. Resulting from the limited amplifier supply voltage, the highest output power is going to be half when you connect an 8-Ohm loudspeaker of the peak power which the amplifier can deliver to a 4-Ohm speaker. Typically maximum output power is given for a 4-Ohm loudspeaker impedance. On the other hand, ideally the maker is going to tell which loudspeaker impedance the output power specification is being referenced to. Please note that a number of amps cannot drive loudspeakers with extremely low loudspeaker impedance.
