My large 2 channel amp has a "stand by" mode. So, it is technically never turned "off". There is always some power within the amp to maintain it at a "close to operating" temperature... This reduces the degree of thermal stresses within the amp from turning it on and off... In standby mode the amp uses 60 watts of power.
