-Class-A Design Circuit-
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-
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.
-True Balanced Input-
Soloist-50 balanced input operates as a differential circuit, and any unwanted noise, hum, or interference common to both lines is therefore canceled.
