The electronics theory that is relevant to cables involves the capacitance of wires and dielectrics and inductance, and of course resistance. The newest materials I know of that are used in cables are kapton and teflon, which have been in existence quite some time. All of the relevant theoretical principles have been well known for 100 years or more (I guess that makes those principles "out-of-date"...too old). As a person who is active in engineering transmitter and antenna designs, you can be assured that I am far more up-to-date on electronic theory than quite a number of people, certainly including you. As usual, your comments lack focus and are generally quite amazing to anyone who anyone who really IS an audiophile (your repeated strange and wondrous comments make it difficult to believe that you actually ARE an audiophile...and the responses to your musings posted in these forums make it obvious that I am not alone in this opinion...).
The "meter" I use for analyzing cable behavior, by the way, is a $40,000 network analyzer that you would probably need hundreds of hours of education and training to have a chance of operating competently. But all measurements are meaningless in your distant world anyway, just as you allege that all CD players sound alike anyway (quote: "I have at least 10 of them and they all sound the same..."-from forum on the AYRE in digital sources forum [condensed from the original due to excessive incoherent rambling...] maybe one GOOD one would be better than your 10...lol).
For a person like you, who has amply and repeatedly demonstrated a VERY limited knowledge of the most basic electrical principles, to suggest that a person in my field has not "kept up" with electronic theory to a sufficient degree to intelligently discuss cables is so ridiculous it makes me laugh. It is like a cow lecturing a supreme court judge on a point of law. If I thought you had the technical knowledge or intellectual abilty to insult me, you might annoy me for a millisecond or two, but as it is...I just laugh and ignore your unfocused attempts at insults. You remind me of the Grelber in the old Broom-Hilda comic strip, who lived in a log in the woods and spent all his time giving out gratuitous insults...striking similarity.
Taking the trouble to respond to the details of your vague and uninformed comments and attempts to insult is like Brer rabbit hitting the tarbaby; one needs to realize that there is nothing of substance there and not take it seriously....
