Which Music Amps Offer The Finest Audio Quality?Selecting a good amplifier for your loudspeakers is not a trivial task. You wish to make certain that your amp matches your loudspeakers. There are models that are as large as half your living room whilst a number of of the latest mini amplifier models are as small as a bar of soap. This allows your amp to be stacked on top of your other audio equipment. There are some core amplifier technologies available. Even today tube amplifiers are still available. Unfortunately, tube amplifiers have fairly large audio distortion which describes how much the audio signal is degraded by the amplifier. Harmonic distortion of tube amplifiers is often as high as 10%. Several of the most popular technologies in the past have been "Class-A" and "Class-AB" technologies. While small stereo amps using these technologies usually have low audio distortion, power efficiency is only 10% to 30%. Amps with low power efficiency will need rather large heat sinks since the majority of the power is radiated.
Another technology is referred to as "Class-D". Latest digital audio amplifiers, on the other hand, employ a feedback mechanism and can reduce the audio distortion to below 0.05%. When choosing an amp, make certain that the output power is adequate to drive your loudspeakers. As a rule of thumb speakers with low impedance offer higher sensitivity. High-sensitivity speakers are simpler to drive to high volume than low-sensitivity loudspeakers. p could get damaged. and amplifier output configuration. positive supply voltage and ground. Besides the supply DC voltage, the amplifier topology in addition has a big affect on the largest wattage since an audio amplifier which drives both loudspeaker terminals (often known as full-bridge topology) can provide four times more wattage to a speaker than a stereo amp which only drives a single loudspeaker connector (also referred to as half-bridge circuit).
