Eric, the author of the study, investigates how noise and jitter in an Ethernet transmission can be affected by ethernet cables and various audiophile tweaks, such as switches, EtherRegen and external clocks, isolators, reclockers, and "better" power supplies, such as those from iFi, etc. Unlike most measurements on ASR that are done at the output of a DAC, Eric measures in the digital domain before the DAC.
The last post in that thread contains conclusions so far. Here's a sample (courtesy Google Translate):
PS: The title of this post is a bit sarcastic, as I think, most here would not find Eric's findings to be a huge surprise
