Frequently asked questions about amplifiers, preamplifiers, integrated amplifiers, power amplifiers, advantages and disadvantages of each type, etc.
Class D advantages are high efficiency, smaller size and lower cost, allowing a proliferation of cheap, powerful amplifiers. This topic is so poorly understood, however, that I’ve written this FAQ just to address the marketing spin and general misunderstandings around it! For those who need the quick answer: Class D is not new and is […]
It depends on the system, sometimes yes, usually no. The sound pressure levels achievable with a hi-fi system come down to two parameters: amplifier power output and speaker sensitivity. These two parameters are inextricably linked. Low-power amplifiers can create realistic sound pressures and dynamics, but only when partnered with sensitive speakers. This all comes down
Are low-power amplifiers acceptable in hi-fi systems? Read More »
Critically important for proper hi-fi performance and dynamic range. This combination of technical parameters determines the actual sound pressure level you can attain without distortion and also tells us a lot about the system’s dynamic capabilities. As usual, science provides the answers. Low Power For example, let’s say you have a low-powered amplifier up to
