Fed up

Here's the problem some of us have, Fred.

We understand the technology. We understand the physics and electrical engineering of signal propagation on transmission lines. We understand how receiver circuits work. We understand how clock recovery circuits work, We understand the mathematics and logic of channel coding. We understand the principles of communications engineering and how to relate channel noise to bit error rate. We understand why the physical layer was designed the way it was, and how the budget (e.g. amplitude and time as embodied in eye patterns) represents various engineering tradeoffs. We have worked on systems other have designed that failed through inappropriate use of edge triggered logic and have learned how to properly design systems that use multiple clock domains. We understand the system aspects of what happens to digital waveforms after they have been buffered and clocked into a separate clock domain. We understand the potential impact of this on the analog output from a DAC. Some of us have designed systems that operate at these data rates and at data rates that are two or more decimal orders of magnitude slower and faster than what are used in digital audio.

Then someone like you comes along, who fails to demonstrate more than a rudimentary understanding (such as I might have understood at age 13) who then puts us down, accusing us of being ignorant or deceptive. When we challenge you to explain the logic behind your arguments, you don't follow through. Some of us are more than a little fed up.
