This device is equipped with the STK4174MK2 chip, which is an improved version of the STK41X1 classic series, a relatively early product with a conservative design at the time. It uses solid materials and undergoes rigorous tuning. The designed output power is 40W+40W @8 ohms, with a distortion level of THD0.4%. Not all extreme parameters necessarily represent good sound, just like many people still prefer the sound of tube amplifiers nowadays. The performance parameters may not be high, but the sound is mellow and delicate, like aged wine, with more flavor as you savor it. Therefore, this time, a classic retro design was chosen, both in terms of sound and appearance, to evoke a retro feel. This device uses a pure copper-wound toroidal transformer, which performs well in the mid-to-high frequencies, striving to deliver a sound that touches the soul.
