How stupid do you think your audience is here?
I think that they are less than educated and / or experienced if what I'm saying doesn't make sense.
Quite honestly, I don't care what their credentials or claims are if they can't grasp the points that I'm making.
Then again, this happens all of the time.
Have to walk in & show the manufacturers & their engineers how their own products work, how to correct issues, refine & simplify designs, improve performance, etc.... using their own test equipment in their own labs or on their own production lines.
When the "big wigs" ask why their own on-site "engineers" didn't identify / rectify certain issues or improve specific design attributes, it's always the same answer: "They did the best that they knew how". Their "big picture" is but one small window on the first floor of a multi-story building that reaches the sky. Their perspective was limited, so they worked with what they knew & could see. Familiarity breeds comfort, albeit limited on a grander scale.
We all have learning curves.
For many folks, their learning curve looks more like a line straight line once the books are closed / school is over OR they have a very slight rise that ascends at a linear rate.
This typically happens when people CHOOSE to become comfortable & get stuck in a rut.
Variety is both the spice of life & keeps one on their toes.
When we stop learning, it should be time to die.
So many folks die an early mental death, even though their bodies are still functioning.
Walking zombies if you will.
Many of those zombies even have degrees.
Degrees that taught them how to think & what to think about, because they never possessed the desire to think for themselves.
The box of their choosing is a coffin, but only for their own mental capacity & level of understanding.
Get outside of the "box" & start thinking outside of the "box".
No need for "snake oil".
Cognitive dissonance does a good enough job of squashing even very basic levels of growth & understanding.
This all acts as one big circuit. Small differences can add up, especially if performance in any given area is marginal.
The more foundational the change, the bigger the potential differences down stream.
No matter how polluted the river, even the simplest of filters can be beneficial.
Even more-so if there were no filters before it & the filtering after it is less than adequate.
Cascaded filtering can only be beneficial, so long as it doesn't restrict the volume of flow.
To increase the benefits of the filtering, one has to know what needs to pass through the filter unhindered.
Beyond that, anything that allows the desirable attributes to pass while limiting extraneous & unwanted characteristics is beneficial.
How beneficial depends on how broad spectrum the filter is, the ratio of filtration & whether or not filtration behind it can deal with what remains.
Either way, the filtration is beneficial, so long as it doesn't limit capacity and / or introduce toxins or side effects while filtering.
In fact, what most consider to be "side effects" of less than adequate conduction for audio signals lay the foundation & are the actual proper design criteria for a good power cord.
