Do Amplifier Class Names Represent Performance Ratings?
No. Nor do the Class letters signify anything. They are just a convenient way of differentiating types of amplifier circuits. For example, “D” does not stand for “Digital” in a Class D amplifier, although there seems to be some conflicting evidence on this. In any case, in discussions, the “D” seems to have taken root as signifying a so-called “digital” design. 6. What Are “Digital” Amplifiers and How Are They Different From Analog Amplifiers? An analog amplifier works in analogous fashion, regulating the output stage devices (transistors) to release power from the amplifier’s power supply to the loudspeakers in a manner that exactly mimics the tiny incoming audio waveform. Digital amplifiers use high-frequency switching circuitry to modulate the output devices. 7. Why Do Some Audiophiles Insist on Tube Amplifiers? Tube amplifiers distort in a different manner from transistor amplifiers, generating musically agreeable even-order harmonic distortion that may lend a sense of so-called “w
