The primary role of an Ethernet cable in an audio streaming setup is to provide a stable and fast internet connection that allows for smooth streaming of audio content without interruptions or buffering. Whether or not an Ethernet cable can make a significant difference to sound quality is a topic with varied opinions. Here’s a breakdown of the considerations:
Types of Ethernet Cables
- Cat 5e: Supports up to 1 Gbps speeds. It is adequate for most audio streaming needs, offering a balance between cost and performance.
- Cat 6: Supports up to 10 Gbps speeds over short distances (up to 55 meters). It has better shielding compared to Cat 5e, which can reduce the chances of crosstalk and interference.
- Cat 6a: Supports up to 10 Gbps over longer distances (up to 100 meters) and has even better shielding, reducing interference further.
- Cat 7 and Cat 8: Offer speeds up to 10 Gbps and beyond, with improved shielding for minimizing interference. These are more than sufficient for audio streaming, but they’re also more expensive and might be overkill for most home audio systems.
Considerations for Audio Streaming
- Stability and Speed: For streaming high-quality audio (such as lossless formats), a stable and fast connection is crucial. However, even a Cat 5e cable is typically sufficient to handle the bandwidth requirements of audio streaming.
- Interference: Higher-quality cables with better shielding can reduce electromagnetic interference (EMI) and crosstalk, potentially leading to a more stable connection. This is more relevant in environments with a lot of electronic devices and cables.
- Sound Quality: The digital data transmission over Ethernet for audio streaming is immune to the kind of analog signal degradation that can affect analog cables. Theoretically, as long as the data packets arrive intact and on time (which is ensured by modern TCP/IP protocols), there should be no difference in sound quality attributable to the Ethernet cable itself.

While Cat5e is sufficient for streaming any high-resolution format (including DSD512), it’s crucial to remember that the overall performance of your network depends on more than just the type of Ethernet cable used. The quality and specifications of your router, network switches, and any other network equipment play a significant role in achieving optimal streaming quality and speed. For instance, using a high-performance Ethernet cable like Cat8 with an outdated or low-quality router will not yield the best results. The router and other network components must be capable of supporting high data rates and managing the demands of high-resolution audio streaming to ensure a seamless experience. Therefore, for the best streaming performance, ensure that your entire network setup, including the router, is up-to-date and capable of handling the speeds and bandwidth requirements for music streaming.
Conclusion
For most users, a Cat 5e or Cat 6 Ethernet cable is more than sufficient for audio streaming needs. These cables offer a good balance of speed, reliability, and cost. While you can invest in higher-category cables for potentially reduced interference, the audible impact on sound quality is likely to be negligible for most listeners. It’s more important to focus on the quality of your audio equipment (streamers, DACs, amplifiers, speakers) and the recording quality of the audio content itself.
