[QUOTE="Hennie, post: 832, member: 20"] Output is determined by your system gain (volume control setting, ampifier gain, music source output, etc.) and speaker efficiency. Power supply variation should therefore not have this effect unless the voltage is so low that the equipment stops working in a linear fashion, but by then you should be able to hear some form of distortion. Human hearing is notoriously fallible and your perception of sound may vary from day to day. Some of the factors which may affect your hearing: - Exposure to high levels of ambient noise prior to listening. - The use of stimulants such as coffee and nicotine - Adrenaline levels - Allergies or sickness, as well as the use of some medicines - Ambient noise level in your room Some amplifier topologies such as feedback free designs are to some extent affected by power drops, but this type of amplifier is rare, and even here the difference should not be that evident.
