"Audiophile Grade" Ethernet Switches - The new generation

[thumb5]

There is a lively discussion in Audiophile Style that talks about jittter from Ethernet and what ASR is doing or not..

Alex popped his head into it, saying that the ASR measuring instrument has too high jitter itself and thus cannot measure when John is trying to do.

It seems from these two posts on ASR that Alex was mistakenly referring to specification for the digital inputs of the AP test equipment, which aren't relevant to the measurement that ASR carried out based on the analog output of the DAC fed by the ER, and that the test gear is more than capable of measuring the levels of jitter UpTone refer to at the DAC clock (whether or not that is the right thing to be measuring).
