Logically, cable reviews of any kind prove bias at least. Of course there is wining and dining by manufacturers like there used to be in the pharmaceutical and auto industries.
I am in recent weeks going through 30 years of cables. Six DACs over 20 years with Blue Jean and two quality levels of Audioquest without hearing any difference.
I purposely use pretty basic speaker cable. Home Depot, Parts Express and Mogami. I may have tricked myself into thinking Mogami was better than Home Depot with Belles.
If a reviewer gets too animated about cables, I find that disingenuous and his or her other reviews suspect.
