To achieve the best musicality a stereo amplifier is preferred over a multi-channel AV amp. This is because of higher quality components such as toroidal transformers.
Amplifiers are responsible for receiving audio signals converting signals and powering speakers.
When looking at amplifiers it is important to consider what sources you need to connect to ensure you have the correct inputs and outputs.
Amplifiers are rated in maximum watts and ohm loads, and it is important to match your power amplifier to your speakers in order to avoid distortion or damage to the loud speaker.
