mosfet...... I can definately tell you that cable construction doesn't come under the classification of semi skilled. 

I think, you also must appriciate that in all walks of life people charge what the market will stand ie if people feel an item represents [in there mind ] value for money then they may purchase. 

I'm not justifing the costs of these cables,  I've not heard or seen them. But everyone has the right to freely sell a product, in the same way you have the freedom to politley decline the offer to buy. 

 It seems to me your never going to purchase these cable for purely philosophical reasons, regardless of there price or performance.  So why make such a big fuss ?
