Indeed. And it would require some actual understanding of how things work.

There is a systematic marketing/PsyOps campaign aimed at discrediting anybody and everybody that dares to criticize the new one true god of systemd. The reason these people are called trolls, are insulted, theri complaints are ignored, etc. is that the systemd proponents actually have very little technological arguments in favor of systemd and none at all for the way it is pushed by force on nearly every Linux user at the moment. At the same time there is a host of convincing technological arguments against systemd, like its immature state, its instable feature set, its violation of a lot of core Unix principles, its inflexibility with regards to kernel versions it can work with, the problems it causes if you want to do something the designers have not anticipated, the unhelpfulness and arrogance of its developers, and outright demented decisions like the binary logs. Hence the proponents of systemd resort to purely emotional arguments because that is all they have. They are then pushing these as hard as they can.

Now, as to why systemd is pushed so hard despite it clearly not being ready for prime-time and it being not the best solution in a lot of scenarios even if it where, that is unclear. One plausible explanation is an "embrace&extend" move by RedHat where they want every Linux installation being dependent in a central place on a piece of software they control. Another is that the NSA and its ilk found Linux far too hard to hack and hence there was the need for a large, complex, network-connected demon that offers a lot of bugs they can then use to compromise systems. And finally, there may be desperate kernel-envy on the side of the chief developer (a known incompetent with a huge ego) who wants to basically wrap the kernel so he can see his own "accomplishments" on the same level as those of Linus.

That is utter BS. A dedicated crystal produces no better or worse clock than a PLL clock derived from a crystal input. You are calling all digital engineers clueless hacks here, when that really applies to you.

Incidentally, you could have learned the same by having a look at a datasheet of a high-quality speaker or mic. But I guess audiophiles do not look at actual facts, as that could shatter their fantasy-world.

It is a system interface test. Quite standard. Requires some actual engineering knowledge though to understand why these are sensible.

Seriously, you have no clue how TCP/IP works. Case in point: TCP has absolutely no error correction. At all. Your statement is complete and utter BS.

TCP has retransmission, but for that to be needed over a single cable hop, the cable needs to be close to complete failure. It basically does not happen. Basically all bit-errors are introduces by broken Ethernet cards and switches. A lot of the drops are caused by overloads and are intentional drops under software/firmware control.

And this is not the only long-term scam that rakes in a lot of money. There are a lot of basically stupid people that still manage to get a decent or even good salary. Society is broken that way.

If you get retransmits because of the cable, then your cable is close to complete failure. Before that you, cables are not a significant source of retransmits. At all.

That is an impressive collection of utter fail. Audiophiles seem to have an even larger percentage of complete idiots than the general population.

None with regard to Ethernet used in a "normal" environment. Seriously, what you claim is religion, not technology.

Bullshit. Unless you get dropped packages, it will make zero difference. If you get dropped packages, the cable is very near to complete failure.

Actually, on analog, gold plating _decreases_ the sound quality, as any crossing from one metal to another one does induce unavoidable noise. Audiophiles generally do not know that little physical fact, because they do not understand audio technology.

And that has what relevance for audio? Right, none at all.

Sure, if noise gets high enough. But at that point the cable will be close to complete failure. Below that level, you get a perfect digital transmission, and that is that.
