IC manufacturer Jinfeng precision high-speed dual op amp, one of which has excellent sound quality

The voice is very brave, warm, charming and sweet. In terms of timbre, it is

The OP fully discrete dual op amp is made based on the Marantz OP circuit. The input uses a warm field effect transistor for precise matching. Previously, because of the large number of components, it can only be used in the discrete pre stage. The board is very large. Now, it is often carefully designed. The bottom area is about the same as that of the dual op amp. The pins are familiar with and fully compatible with NE5532 MUS02 OPA2604 LME49720HA and other op amps

Operational amplifier features:

1. There is no low open-loop gain, so there is no need for deep negative feedback like the op amp, and the sound is more natural and delicate

2 Larger output current. Generally, the output current of the op amp is about 40MA, and the output current of this op amp is 100MA

The actual personal listening compares the voice roundness of OPA2604, OPA2107 and other operational amplifiers HDAM. The voice roundness is good, and the sound permeability is good! Tri band equalization, excellent performance in details! Fine changes can be shown! Fully extensible awesome! The space is full of sense of presence

The effect of each machine depends on the whole. The design, power supply and materials are very important. Therefore, some people have greatly improved after replacing the amplifiers. Some people can't hear it when replacing the amplifiers of N brands. The bottleneck is not where the amplifiers are. If they can't hear it, they will cry fake. It has no effect. It is an improper evaluation. According to the customer's feedback, Zishan has been polished and wants to improve significantly on DAC, XD 05, slot cards and other machines, but it is difficult for some domestic AV machines with bottlenecks to show significant efficiency.
