This is the most linear of the amplifier classes, meaning the output
signal is a truer representation of what was imputed. The output
device (transistor) conducts electricity for the entire cycle of input
signal. In other words, they reproduce the entire waveform in its
entirety. These amps run hot, as the transistors in the power amp
are on and running at full power all the time.
Because of these factors, Class A amplifiers are very inefficient for
every watt of output power, they usually waste some watts as heat.
Because of the watts of heat energy released they run very hot,
needing lots of ventilation. But the upside is that these amps are
the most enjoyed of all amplifiers. These amps dig out musical
detail, since the transistor reproduces the entire audio waveform
without ever cutting off. As a result the sound is cleaner and more
linear; that is, it contains much lower levels of distortion. They are
the most accurate of all amps available.
Dual mono design topology. This gives the amplifier better isolation
between channels. Soundstage imaging is improved, offering true
soundstage width and depth. Instrument placement and layering
are more accurate.
The traditional potentiometer is implemented with an electrical
contact that slides over a resistive layer that cause the problem such
as quality of the electrical contact, consistency between separate
audio channels, sensitive to dust. DSA Volume ( Digital Controlled
Step Attenuator Volume) using discrete resistors and relays as
switches solve those problems and improve quality of sound.
Soloist-50 balanced input operates as a differential circuit, and any
unwanted noise, hum, or interference common to both lines is
therefore canceled .
