Digital cable, and why it is not only data

A digital cable either delivers the data or it does not, but that is only half the story. Timing errors and electrical noise travel along the cable alongside the signal and arrive at the DAC, where both affect what comes out of the analogue stage. This is why digital cables can sound different from one another despite carrying identical data.

Choose by connection first. USB is the most common link from a computer or streamer to a DAC. Ethernet carries network audio and is the fastest growing area in digital hi-fi. Optical isolates two components electrically, which helps where noise is a problem, but has bandwidth limits at high sample rates. Coaxial S/PDIF generally handles higher rates and keeps a direct electrical connection. AES/EBU on XLR is the professional standard and appears on higher end transports and DACs.

Impedance is not optional on coaxial and AES/EBU, at 75 ohm and 110 ohm respectively, so a standard interconnect is not a substitute even though the plugs fit. Tell us the source, the DAC and the sample rates involved and we will tell you which connection to use.

For noise isolation, yes. While Ethernet transmits data efficiently, it can carry noise. Fibre breaks the electrical path, reducing interference.

Coaxial S/PDIF uses RCA or BNC connectors with 75-ohm impedance, while AES/EBU is balanced and uses XLR connectors with 110-ohm impedance. AES/EBU typically offers better noise rejection for professional and high-end systems.

Optical TOSLINK cables are ideal for preventing ground loops and electrical interference since they use light transmission. Coaxial cables, however, often deliver a slightly more robust and detailed sound.

Yes, but not in the same way as analogue cables. High-quality digital cables minimise jitter and ensure stable signal transfer, preserving timing accuracy and reducing noise.

Yes. Both coaxial and AES/EBU cables can handle 24-bit/192kHz audio, while optical cables may be limited to 24-bit/96kHz depending on the device.

Using a true 75-ohm coaxial digital cable maintains impedance consistency and reduces signal reflections that can introduce jitter and distortion.
