The amplifiers efficiency is the highest efficiency I have ever tested. Especially at 2 ohms
where efficiencies can hover between 25% for conventional Class AB output stage to
35% to 45% with a tracking supply depending on the topology of the tracking supply.
BCA amps average 60% at 1/3
rd
power 2 ohms. SO this is one step in efficiency above
that. At almost 80% efficient this about 90% power supply and 90% amplifier.
At idle the amplifier only consumes 35Watts. While the output stage active.
Sleep mode is not necessary in this case. This represents audio signals with signals
heavily clipped. Most music signals only approach or exceed these levels briefly.
