Note: At present, the CD-Ripper only supports the use of JF Digital MX series players     The CD ripper is the second generation product, which has better sound quality and more convenient operation than the first generation product. CD ripping also needs to solve the supporting information such as album cover, song name, etc. We have made a set of simple and practical management software to solve the supporting information of CD ripping according to actual needs. As long as the user...

What is carbon fiber diaphragm? A new generation of expensive diaphragm closer to the sky high diamond diaphragm As the name suggests, it is a horn unit diaphragm made of carbon fiber. The ideal diaphragm needs to have the characteristics of light weight, large Young's modulus, pleasant damping and small split vibration. The key point is that the forward and backward delay of vibration should be appropriate. Carbon fiber material, with molecular structure similar to diamond, has high rigidity,...
