Title: Defies the laws of physics?
Review: Despite the carefully worded description of the physics of light transmission, I found the TOS to TOS ILS200-1M made a significant difference in the sound quality compared with that of the OEM cable supplied by SONY. While the explanation of the physics is correct, the writer doesn't allow for variances due to execution. For example, very minor impurities in the materials that make up the body of the signal distribution unit can cause enough back flash to degrade/contaminate the signal even at the speed of light before it arrives at its destination. The wavelength of light and the frequency of this noise are not related. Granted, in most consumer quality FO cables, this is a very minor component of the delivered signal; does that justify spending $40-60 more for a HQ cable? That's a matter of personal preference and the capability of your biological sensors. In my case I think it was worth it as a luxury.
Is the review positive or negative?
