While i basically like Richard Vandersteen and know first hand how opinionated he is, i tend to disagree with his findings. EVERY solid state power amp that i've ever owned sounds better after being left on for at least 24 - 36 hours or so. As to the original question about leaving gear turned on while "browning out", i would not think twice about it. If they are literally dropping power output i.e. voltage for periods of time, my equipment would be turned off when not in use. Low voltage can cause just as much of a problem as overvoltage. Some circuitry can become unstable under low voltage conditions and begin to oscillate. I would rather live with slightly worse sound for a period of time than have to worry about having to repair or replace my equipment. The bigger question is "WHY" are you still experiencing brown-outs and "WHY" hasn't there been a class action suit against the power companies for not providing the needed power ??? Sean
