Independent pure class A power supply for left and right channels, silver-plated oxygen-free copper high-quality wires, large-capacity filter capacitors Replaceable op amp design for high playability

The quality of the power supply determines the basis of the sound quality. Only when the power supply is good can we talk about other aspects. The use of a class A voltage regulator circuit, low ripple, low internal resistance, two customized audio sealing cows, plus a total capacity of 60,000 microfarads. NOVER capacitors should be used for filtering, so the effect can be described as stable and calm. The amplifier circuit adopts a replaceable op amp design, which can be replaced with different single op amps according to personal taste.

The random distribution is the classic 5534. The machine has a pass-through design. You can choose the tone adjustment circuit or the unadjusted pass-through circuit. Adapt to different adaptation scenarios, with strong compatibility. The decoupling capacitors use ELNA audio capacitors, the sound is delicate and smooth

The wire inside the machine uses Teclon silver-plated oxygen-free copper wire, which not only looks beautiful, but also significantly improves the sound quality. The terminals are made of Taiwan-made gold-plated RCA,

which is not easy to oxidize, looks like new, and shines brightly. This reduces the loss of sound quality to zero.
