The JA-50 mono channel power amplifier is the sub-ordinate flagship model in JungSon's Class-A amplifier fleet, which inherits the flagship model JA-100's appearance, functions, components and similar sound quality, but has a slightly smaller size and power output. Same as in JA-100, the front panel of JA-50 is made from high class stainless steel with remarkable craftsmanship, which makes it everlastingly mirror-shine and stunningly attractive.

The JA-50 utilizes a symmetry Class-A circuit with fully balanced transmission and amplification, thus it provides powerful performance of a hi-end hi-fi amplifier. All components and parts are from world famous brands, and selected to be exactly identical in pair from numerous individuals. It allows the original signal to be truly and naturally reproduced and music maintains equilibrium at high, mid and low frequencies. The JA-50 produces pure, deep and full music with a precise and broad sound stage.
