Thanks, Richard (Ricred1).
The kinds of effects that can be involved are not even well understood by many practicing EEs. Which is why a textbook and course on High Speed Digital Design that were created by a noted authority on such matters, which I took in connection with my work a couple of decades ago, was sub-titled "A Handbook of Black Magic."

In my humble opinion one part doesn’t equal same performance.No question about it. There are of course countless variables and tradeoffs that contribute to the overall performance of a design. And, hypothetically speaking, even if the entire design of a DAC from each of two manufacturers was totally identical from an electrical standpoint, the two components still would not be likely to perform in an identical manner. Even differences in how signals are routed within the printed circuit board, and how the board itself is constructed, can affect performance significantly. That is especially true when digital signals are involved, which have very high frequency components associated with their risetimes and falltimes (i.e., the amount of time it takes the signals to change between their two voltage states). And even more so when that circuitry is in close proximity to analog circuitry.
