Yes, sure, those things are hard, and they have nothing whatsoever to do with the quality of passive components like cables, as long as they are not in the failure range. Or anything to do with working-transceiver quality except when it comes to the clocks that the transceivers are using.

When you talk about jitter introducing significant distortion based on packet timing, that's something that can only happen in two ways: either the audio receiver is using an absolute garbage clock, or it's using an absolute garbage and shortsighted algorithm for adjusting its clock rate, and not trying for a stable sync. The quality of transceiver and cable components is not a factor.
