Kijanki -- You raise some good points, and also some that I see somewhat differently. I too, by the way, have been an audiophile and in electronics (not related to audio) for around 30 years.
This is how I see it:
-- You have a good point about cable "disappearance" correlating with a short cable sounding the same as a longer cable of the same type. But I would expect that very few people assess cable differences that way.
-- I believe there are many more factors involved, both known and unknown, than inductance and capacitance. Just to cite one example, which I mentioned in another recent thread, what is called "spectral contamination" caused by intermodulation effects resulting from ultrasonic and rf interference coupling. See
http://wiring.svconline.com/ar/avinstall_designer_cables_critical/index.htm-- Certainly a cable that has a shield grounded at only one end can be expected to be directional. I made the very same point in the current thread about fuse polarity. I assume, btw, that you are referring to single-ended interconnect cables that have both an inner shield and an outer shield, with the outer shield being the one grounded at only one end. If there were only one shield, as might be the case in an inexpensive cable, there would be no (direct) signal return path if one end was not connected.
-- I believe that system synergy is important at all price levels, as Mapman stated well.
-- Partially as a consequence of that, I believe that while some degree of correlation obviously exists between cable price and cable performance, it is far from a perfect correlation (i.e., the correlation would be well below 1.0 if it could be expressed mathematically).
-- I tend to take manufacturer claims and literature with several large grains of salt. Partly because it stands to reason that it will be self-serving. But also due to the fact that as a person with a technical background I feel that much (though certainly not all) of the contents of technical "white papers" and other manufacturer literature, and the technical explanations that are offered to account for the claimed differences, often approach (or actually reach the point of) being utter nonsense. Examples that fall into this category, in my opinion, are articulation poles, golden ratios, and time alignment. I certainly don't mean to imply that the makers of those cables don't provide excellent products, that will provide good performance and value to many users, just that the explanations are speculative at best, and utter nonsense at worst. And as a potential customer, I find that sort of thing to be a turn-off.
-- I think it is pretty well established that even in the case of the most sincere, open-minded, and perceptive listener there will be a correlation between what is heard and what the listener is expecting to hear. One reason for that may be increased concentration being brought into play when the cable that is expected to be better is being listened to.
-- Another factor that probably misleads many listeners as they assess cables or other components over time is failure to recognize and control extraneous variables.
-- While I don't believe in "evil conspiracies," I do believe that manufacturers take advantage of our natural expectation that more expensive = better, in combination with the fact that cable differences are elusive, system dependent, and to a large degree unexplainable by conventional science, to hype unnecessarily expensive product with bad science.
