I did not link the article believing it to be an authoritative dissertation but to foster in those skeptics at least some curiosity by lending support to the idea that cables can sound different.
No - I did not read his background. I read the article. And I found it to be rational as what he references are all things that can be supported in theory and measured in practice. The debate is not whether these things exist but whether they are audible.
As you didn’t dispute anything he wrote, why dispute his background? If your standard requires that someone be properly degreed, then there are additional questions which must be posed. Degreed in what? Electrical engineering? Physics? Materials Science? And what school will be acceptable to you? And what about those who are gifted but choose not to finish their schooling?
It’s fine to be a skeptic. Indeed, I used to be one. For years, I held the strong belief that power cables mattered not at all. I ultimately had to come to a different conclusion. Heck - I heard a difference and still struggle with it conceptually as they’re no where near as obvious as speaker cables, but affect a sonic change nonetheless.
