This device uses Sanyo's original thick film module, which is known for its full tone and prominent mid to low frequency intensity. The high frequency is delicate and not harsh, and the overall listening experience is better than most integrated chips (such as LM3886, TDA7294), especially in terms of voice and instrument performance, it has a more "analog flavor". Its low-frequency dynamics and analytical power are comparable to high priced discrete component amplifiers when paired with high-quality power supplies and capacitors. The total harmonic distortion is low, approaching the level of top-level discrete circuit design, and stable performance can be achieved without complex debugging.
This device utilizes a high-power stereo thick-film audio power amplifier circuit produced by Sanyo.The core utilizes the Sanyo thick-film module STK426-090, with a power of up to 100W per channel and a THD (Total Harmonic Distortion) of only 0.04%. The actual sound quality is low-pitched, warm, and pleasant to listen to, with no lack of clarity and full power.
The PA-425 module is an STK425-130 with a power output of up to 130W per channel
