What is the product?

The iSO-CAT7 is a product that improves the performance of the iSO-CAT6, which was used as a necessity for all  audio systems that use LAN ports. 

How it performs?

If you listen to music using the iSO-CAT7 in your system, connecting it to the network player which, is the most important part in the network audio system, you will be able to understand what it means to refine digital sound closer to analog sound. This is not just simple improvements in specific parts of the music, but clear changes in sound that causes the illusion of reconstructing sound of the entirety of the music or listening to another recording of the same music.

How it is made?

specially selected parts to shape and refine the audio were chosen and each of the four Ethernet signal lines embedded in the Ethernet cable are separated and shielded to reduce interference between each signal line as much as possible to lead to a definite improvement in sound quality.
