I don't know if I'd go that far. After all, reviewing A/V equipment is likely one of the most challenging tasks since its both a matter of taste as well as a technology. Car reviewer also comprise this group.

In cases like these, its really important to find reviewers you can relate to and trust; someone who looks for similar aspects in functions and quality as you do. Its definitely not something you should do quickly, since getting to know a reviewer (and his integrity) takes time.
