I can accept it costs more to produce better performing components. But there is some voodoo physics in "high end" products. One example is speaker cables costing tens of thousands of dollars. The issue of skin depth attenuating high audio frequencies is an example that can be easily calculated. A pair of 8 gauge solid cables has the resistance changing from 0.005 Ohms for DC to 0.01 Ohms at 20 kHz for typical lengths. This in series with 4 speakers attenuates signal voltage by less than 0.01 Db. Cable marketers caught in this junk science lose all credibility for me. There are other claims: differences in signal path length of a few millimeters at the speed of light smear the sound and stored static dipole polarization in loudspeaker insulation can be tested by putting the insulation next to another cable with the speaker disconnected. The first cable is connected to the speaker and not to an amplifier. Such stored dipole energy from one insulator should be possible to hear in the connected speaker if insulation were an issue. It does not.
