The PA-49 is designed to meet the high demands of Hi-Fi listening. With a preamplifier stage for sound output and a power amplifier stage for power output, the preamplifier circuit of the product draws reference from the renowned Japanese Accuphase C3850 model, which costs tens of thousands of yuan. It features a large open-loop gain, a diamond-shaped architecture, and Class-A front-end output, delivering exceptional detail reproduction and a sense of airiness. The power amplifier stage employs a classic thick-film circuit, offering highly elastic low frequencies and exquisitely detailed high frequencies—a powerful audio combination!
This unit employs the original Sanyo thick-film STK417-130 audio integrated module, which boasts extremely high precision, powerful output capacity, minimal distortion, stable performance, and excellent heat resistance. In the early days, many renowned manufacturers utilized this module. Its sound quality is mellow, delivering rich and full-bodied audio effects that are more orthodox than the sounds produced by common integrated circuits and transistor circuits.
