Four pairs of NXP high current transistors
Easy and free
In addition to the ES9018K2M DAC chip and OPA1612 operational amplifier chip, we also added four pairs of transistors with
highest current of 2A to make the open loop current increase by 10 times. As a result, the current driving capacity increased greatly,
the sound output is easier and has allowance, the transient performance is excellent, powerful and accurate and the control force
is powerful. At the same time, we designed the whole main board again and specifically marked out a 6.1% area for the Hi-Fi part
so as to fully spread out the circuit element. The thermal stability is excellent and the distortion and noise are decreased further.
