These threads are always funny.
You can spend $500-$1000 treating your sidewalls or ceiling and it will have 10x the improvement in your system than spending $5000-$10000 on cables and doodads.
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. |
