[The advantages of separation]:
Each transistor of the op amp operates in a linear region, so that the audio amplification is perfectly linearized, and there is no difference in the slew rate caused by the input voltage. This is the reason why the high frequency is not harsh.
This op amp uses the front, middle and rear third-level Darlington structure amplification circuit, not only to make the input high impedance. And each stage of amplification response time is very fast.
Since the compensation capacitor is added to the op amp circuit, the consistency of the low-frequency amplification is perfectly matched, and there is no problem that the low-frequency amplification compensation time is not enough. This is the deeper reason why the low-frequency is more powerful.
There are a lot of secrets for expensive amplifiers that don’t require an integrated op amp, with a discrete device set linear amplifier output. The reason is that the integrated op amp is made on a piece of silicon, which has the advantage of high integration but also has disadvantages. Because the cross-tube on the silicon wafer is not the same as the beta value of the vertical tube, it is very difficult to add a resistor on the silicon wafer, and the discrete device op amp just makes up for this shortcoming and is perfectly balanced.
