The price is the price of a single MUSES02 op amp: the conscientious price, other pure profiteering JS that sells more than 100 yuan. Announce it. The white letters and dots are made in Shenzhen. You can buy them and compare them carefully with our shop. It’s not the case at all. The authentic ones are gray and the dots are bright, and the white letters are all polished products.

MUSES02 Japanese factory,
In terms of sound quality, New Japan Radio has always insisted on "improving sound quality" and "extensibility of reproduction space", combining circuit technology, graphics design technology, and New Japan Radio&x27;s audio IC technology to select frame materials to successfully develop The MUSES series of products.
The effect of a machine depends on the overall design, power supply, and materials used. Therefore, some people change the op amp to improve greatly, and some people change to N brands of op amps. The bottleneck is not where the op amp is. If you can&x27;t tell, you will shout fakes, to no avail. It is an improper evaluation. According to customer feedback, after polishing Zishan, I think the DAC, XD 05, Tiger Card and other machines have improved significantly, but some domestic AV machines are difficult to achieve significant performance on machines with bottlenecks everywhere.
