Most sound sources emit sound in stereo: left and right. Stereo amplifiers have two inputs per sound source. The stereo amplifier emits the sound again in two outputs, for both speakers one.
Surround amplifier / receiver
The Surround amplifier Can also be used as a stereo amplifier. However, these has additional outputs, so that the sound can be broadcast to multiple speakers. This amplifier is especially popular in systems where the home cinema is central.
This type uses transistors to translate the electronic signal. Due to many people, the sound that is produced by this is described as less colored, compared to a tube amplifier. So more realistic. In addition, they are generally more robust and cheaper.
A tube amplifier, translated the electronic signal by means of tubes. As a result, the sound is often experienced as more colorful and vividly, compared to the transistor amplifier. Because it gives a certain character to the sound, it can be described as less realistic. It is up to the listener where preferred.
Class A Amplifier
Amplifiers can be divided into different classes. It is often thought that amplifiers with a higher class offer better sound quality. However, this is not the case. At class A amplifiers, such as those ofSugden, the transistors are always in guidance. Because there is constant current through the amplifier, even when no sound is played, many people experience this as a very nice sound.
Digital amplifiers do not use tubes or transistors. They translate the sound via digital components. The incoming sound is digitized and is only translated to analogue at the last minute when it goes to the speakers. Due to this perfect translation, digital amplifiers are generally considered very realistic.
Amplifier with DAC
DAC stands for Digital-to-Analog converter. This type of amplifier is mainly used when digital audio sources are central, such as computer, television and CD. The amplifier makes an analog signal from the incoming one and zero.
Receiver with Streamer / DAC
Because the streaming of music becomes increasingly popular, we see more and more receivers with a streamer and DAC. The streamed music will be received digitally and goes out again with a rich analogue sound.
Do you often listen to music through your headphones? Even then you want the best achievable sound quality. Many portable music players or phones give too little tension on your headphones for a high quality sound. Theheadphones Strengthens the electronic signals on which your sound is deformed considerably less and sounds better.
