Could it be said, then, that science has not addressed these audio differences or have only been studied at higher level technogies (sat and communications, biomedical, military etc.) with more complex signal demands? Audio study at this level could or may have been done and determined it of no merit. Are other properties (not in the normal power supply 101 courses) impacting the signal? I doubt the AC static and magnetic energy effects have an impact on sound with a properly built psu. I am ignorant enough on this topic to admit it and ask. I have had power courses in HS, Navy (IC), Computer repair, Electrical union and factory design courses. None of these courses discuss power impact on signal quality (other than thru the power supply performance) except by fluxuation of potential and phase timing, to the best of my memory. These classes were 30 years ago. Have things been discovered that have changed? Any treatment of extrainious contaminants were done at the psu/filter and shielded components. Everything in the signal generation section was made and transported internally thru the power supply.
Sampling is the only way of knowing what impact this has. At least this product can be auditioned before purchase.
Enjoyment of a spirited debate can motivate folks to extend efforts to find answers so lazy folk like me can benefit

. That's what is so cool about this forum. Personal qualifications for those giving an answer to a question should not be an issue, the source and validity of information is. If we are all arguing about opinions or wrong training, I can see why this turns into a FFA. But we have the industry expertize here to debate the physics of the topic.
Why do these debates generally get terminated? Moderators can keep on topic or remove offensive posts. Or, do we not want to know the answers on a public forum sponsered by influencial vendors?
