<font color='#000000'>A "white paper" is not necessarily a scientific or technical document. It might just be a marketing piece in a lab coat. Has it been previously published in a recognized peer-reviewed journal, or is it at least based on sources that have been published thus? Are the sources cited?
Things like skin effect and characteristic impedance are only concerns at radio frequencies (skin effect might have some very slight bearing at the highest audio frequencies, but even this is controversial -- Gene might take issue with me here!).
For that matter, are their claims re: their clients true? I can claim to have a PhD in physics from MIT on my Website* but how many of you would check up on it? For that matter, would MIT?
It is common for cable vendors to cite phenomena that are valid concerns for cable when used as RF transmission lines or for high-speed data transmission but that have no bearing on audio.
Conclusion: clever snake oil, but snake oil nonetheless. Especially at their prices!
