Betsy, reading your message I assumed for a moment that you must be a Forum moderator telling me what I am allowed to write. But you have just two posts, so it seems you are not, and I will disregard the second line in your message.
I will also assume that you are a private enthusiast like me with no commercial affiliation.
So, we have dCS saying that “Audiophile Ethernet switches are a solution looking for a problem.” (Andrew Papanikolas July 2019)
And then in your first post on the dCS forum you write: “Night and day difference, background is beyond blackness”; “One of the best upgrades I have done, just priceless sonics.”; “Highly recommend Jord, his team is fast professional and masters of electronics at Pink Faun.” and add the website, then a well formatted upgrade list, including labor and small parts.
I checked the website, saw the galvanic insulator, and got intrigued: I think I will give it a try.
But the clock? What improvement may come from an improved clock when “The Network interface runs in asynchronous mode” (taken from the dCS Rossini manual)?
About the reference to the alarm clock: many years ago some audiophiles were sure that putting one thing that looked suspiciously like a toy alarm clock (and was in fact a toy alarm clock) anywhere in the listening room would improve sound. And if you purchased two alarm clocks, it was even better. And so on. In principle, you might improve SQ indefinitely for the cost of an adequate number of alarm clocks.
So with my audiophile friends we said “yes if you put the AC in your car it will go faster, if you study close to the AC you will get higher marks,” and so on. Was kind of a recurrent joke.
No offense meant, but every time I hear the words “let your ears be the judge” with no technical rationale offered, I think of the magic Alarm Clock. Ready to change my mind if a scientific explanation is offered.
For the record: many Alarm Clocks were sold, and according to some sources, someone bought three of them.
Regarding your final question: my research field is not close to OCXO; it’s closer to polynomials over Galois fields, the theory behind Reed-Solomon codes, which in turn are related to crc codes used in data transmission. I think there is no use here showing off titles, academy, scientific papers and so on: this forum is for friendly people who share a common passion.
Best
