California electrical shortage audio

California is experiencing an electrical power shortage and has random brown outs. Many current audio products are now designed to be left with the power on (they say producing no harm or wear to the unit). Many manufactures recommend that leaving the power on allows the circuitry to remain at a constant operating temperature, providing better performance and longer life. Should I continue to leave my CD Player and integrated amplifier on in mute mode considering the California electrical power shortage and random brown outs? thanks...
