So all digital cables are equal? Including coax, toslink, etc? Its all just digital packets right?

This pretty much destroys your initial premise... @frank009

Cable impedance matching (75 ohm for coax), shield quality, and connector quality all affect signal integrity at the physical layer in ways that influence jitter at the receiving end. Even with jitter rejection in the DAC, you're asking that circuit to work harder with a worse cable, and no rejection is perfect. For USB, noise on the cable's power lines can couple into the source device's clock domain. Shielding quality matters for RF rejection, which affects the noise floor of the entire receiving circuit. Cables affect the analog output through timing and noise mitigation that are real and measurable, even when data integrity is perfect. |
This thread is about Ethernet cables. As far as Ethernet is concerned, one run of SFP fiber between router / switch and streamer effectively eliminates all parasitic noise, and since TCP/IP is an unlocked protocol no timing issues can possibly exist up to the input of the streamer (the output is a different story). Add to that the fact that streamers buffer 1-2 minutes of data (it’s data not music until it exits the DAC) and the odds that the titular $3,800 Shunyata Ethernet cable will have an effect on sound quality are absolutely nil. But it’s a beautiful cable, and there is nothing wrong with audio jewelry. |
