The most efficient power amp up until now is Class D design. It is a digital amp, which the output mosfets are only in 2 stages, on and off, within certain period of time. Efficiency can be up to 85%, so the amp will be cool even if we pump alot of power from it. This is usefull in lowbass frequencies, when the energy is the most demanded.
