The 2nd responsibility of your stereo amplifier will be to present a low impedance at its output plus simultaneously a relatively large impedance at the input. The sound quality which you can obtain from the loudspeaker would depend a great deal on your music amp itself as well as the quality of your loudspeaker. When you are seeking an amp which is fairly compact, then Class-D amps are possibly the ideal choice. Those ultra miniature power small amplifiers out there normally will not have external heat sinks. Keep in mind, though, Class-D stereo amps do not offer the same audio quality as their analogue cousins. It is because the switching architecture inside the amplifier introduces a few components which tend to distort the signal to some degree. Though, music distortion might not invariably result in bad sound considering the fact that tube amps, as an example, additionally possess a pretty large amount of distortion but nevertheless are preferred amongst audiophiles. Due to this fact, analogue amplifiers like Class-AB music amplifiers generally have lower audio distortion in comparison with switching amplifiers. The primary downside of analogue power amplifiers compared with switching amps is the low energy efficiency. Since analog stereo amplifiers dissipate a great deal of energy as heat, there should be some device for the heat to radiate.
