Есть такой чел.. Roger Russell.. на протяжении многих лет был акустическим инженером/дизайнером небезызвестной компании McIntosh. Написал большую и познавательную статью о шнурках..
Понравился абзац:
If I don’t believe that expensive speaker wire makes an audible difference, why is it used inside the IDS-25 speaker system? The answer is very simple. IDS is out to sell speakers and not everyone believes in ordinary wire. The explanation is the same as what McIntosh found at shows and is described in the section above. Cardas wire does not sound any better but it may help to sell speakers to those who are concerned about wire and are not convinced that ordinary wire is just as good. The increase in cost is negligible compared to the drivers, enclosures and equalizer.
