Busted! Reviewer copies manufacturers sales page in review?

I'll sometimes look at reviews in these publications as just one of a great many sources of info I go to when researching for something new. I'll take any one thing or opinion with a grain of salt, as I look for some kind of general consensus. 

One person's 'best' can be somebody else's 'worst', so that audio mags should still be worthless with totally subjective 'best' v 'worst' comparisons, unless you're talking purely about measurements.
