The type of amp you choose can have a huge effect on sound quality, power consumption, and cost. Here's how the Yamaha A-S301 ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for ...

Another study focused on improving the power supply rejection ratio ... Research has also explored the use of Class-D amplifiers in specialized applications, such as driving piezoelectric speakers.
