* C10100 - also known as Oxygen-Free Electronic (OFE). This is a 99.99%pure copper with 0.0005% oxygen content. It achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment. Silver (Ag) is considered an impurity in the OFE chemical specification. This is also the most expensive of the three grades listed here.
* C10200 - also known as Oxygen-Free (OF). While OF is considered oxygen-free, its conductivity rating is no better than the more common ETP grade below. It has a 0.001% oxygen content, 99.95% purity and minimum 100% IACS conductivity. For the purposes of purity percentage, silver (Ag) content is counted as copper (Cu).
* C11000 - also known as Electrolytic-Tough-Pitch (ETP). This is the most common copper. It is universal for electrical applications. ETP has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has 0.02% to 0.04% oxygen content (typical). Most ETP sold today will meet or exceed the 101% IACS specification. As with OF copper, silver (Ag) content is counted as copper (Cu) for purity purposes.

Many owners of high-end audio and video equipment value oxygen-free copper. Behind this demand is the belief that oxygen-free copper will have enhanced conductivity or other electrical properties that are significantly advantageous to low frequency (audio) signal transmission. However, conductivity specifications for C11000 ETP and C10200 OF coppers are identical. In practice, nominal conductivity differences between the three grades listed above are less than 1% at room temperature.
Les défauts des câbles blindés viennent du comportement capacitif et inductif (dans une moindre mesure) de ce câble.
Et ça, ça tient au matériau de l'isolant (qui se comporte comme un diélectrique), a son épaisseur, et à la structure du blindage.
Le reste c'est du marketing.

"Oh justement, moins on en sait, plus on est capable de réellement juger quelque chose. Je suis peut-être pas expert en art, mais j'ai deux yeux, comme tout le monde, je sais distinguer un truc moche d'un truc beau comme n'importe qui d'autre.
Si Van Gogh a passé toute sa vie pauvre et incompris, c'est parce qu'il faisait de la merde, point, il ne savait pas peindre. Des années après sa mort, des "experts" ont décidés que c'était un génie, ça ne change pas pour autant son travail." (King V expert es bon goût)
