Another thought (rhetorical question)...given the benefits of XLR in pro audio over long distances, why would high-end home audio designers bother implementing XLR if there was no sonic benefit over relatively short distances?
The diagram came from the article in my first post above.
See article below:
@ditusa the article from Ralph was interesting and answers the question I asked about the benefits of XLR in home audio. Comments about cable auditioning were also interesting.
Comparing the same cable RCA vs XLR may also be interesting.
