Hi Andy, I've an EE degree, I sure know about buffers and TCP/IP protocol to ensure data correctness. However, just as the engineers invented SPDIF didn't think people can hear the effect of jitter some 30 years ago, I'm suggesting that latency will cause more jitter to be produced on the PLL. It is a theory from my friend, who is a high-end audiophile and senior engineer by trade. To quote him: The latency causes the uneven filling of the buffer may lead to PLL perturbations, ending up in jitter at the output of the PLL. Imagine you have a tub with a drain hole at the bottom. Your job is to keep the flow rate constant. So you use a valve and adjust the valve to regulate the flow. At the same time if you add water to the tub by throwing cups of water into it, the flow rate through the valve will be affected, even if you are at the control. The effect of what earwaxer hears is consistent with what I've heard when jitter is removed from the system using Big Ben reclocker, removing noise induced jitter on AC line by isolation transformer and power regenerator, etc. In my case, wired or wireless is the same, because I've a Big Ben with a custom made linear power supply for removing jitter from the Transporter. -- Kuro ------------------------------------------------------------------------ Kuro's Profile: http://forums.slimdevices.com/member.php?userid=16701 View this thread: http://forums.slimdevices.com/showthread.php?t=74721 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
