Advantages of some key features-
Our exclusive single-ended "Advanced-Class-A" amp-circuits
with following advancements:
1- shortest signal-path because of only one single-ended amplification-stage
2- output transistors are never leaving the operation point
(no zero-crossing therefore no crossover distortion )
