In high-fidelity systems, the quality of equipment such as loudspeakers and amplifiers is the most important. In detail, it depends on how well electrical input signals can be amplified with the minimum distortion and then how excellently the amplified signals can be converted to reproduce musical sound with high-fidelity. It is, moreover, equally essential to have a reliable system that can control and dissipate unwanted vibration from audio equipment to deliver the best outcome of the sound.
