There are already a number of network audio devices on the market, but it would be fair to say that none of them yet have Ethernet ports designed for audio purpose.

When USB audio devices were available on the market more than 10 years ago, there were many questions about the practicality of audio purpose USB cables or like the USB host card products. It's probably because people thought that the digital interface only transmits data represented by 0 and 1. However, these audio purpose USB products are now the basis of digital audio systems, and the audio-purpose network card, sNI-1G, will also play an indispensable and important role in digital audio devices.

There are high-frequency noise flowing from the network port, and it can be beyond our imagination.  Since it is noise of very high frequency components, it passes through various devices and parts to the DAC’s circuit, and results in deterioration of sound quality. Without understanding this process, it will be difficult to find out why you should use the network card for audio purpose.

Although noise from AC power line is commonly known, the noise from Ethernet port  is different from that of AC power, so careful technical review is required for Ethernet port.

This carefully reviewed network port, sNI-1G, provides a complete transmission of network audio streaming, as well as a very clear improvement in medium-to-low transparency and the instrument's texture and wide-to-deep stage expression, enabling you to experience a completely new level of sound.

The sound quality improvement achieved using the sNI-1G network card cannot be compared to a trick that can simply be achieved by replacing interface cables or by one or two parts. This is because it is designed by combining deep computer system knowledge and circuit technology with digital and analog audio, which is why sNI-1G is essential for all network audio.

Enjoying music and understanding music can be done with not the best sound quality, but with a typical network audio device. However, music playing through the sNI-1G, which is able to perform the best sound quality through network audio system, will give you a sense of joy and feel depth of music.
