The "how many reviews it got" rule

Does anyone has an example of a component that had
a lot of reviews but turn out to be bad? Based on
what I've seen over the years, if a component had
a lot of people reviewed it, most likely it's a good
component. Such website like www.audioreview.com
which posts reviews of regular users is a good
indication as well. I notice if something that
has a lot of feedbacks from users, it turns out
to be good as well.

It's akin to writing a reference letter or a letter of recommendation. If a student asks me for one and I have negative things to say, I'll pass on writing the letter rather than writing a negative letter. If I really have to write one, I'll couch it in generic terms that admissions can plainly decipher, but that don't openly condemn.
Reviews strike me the same. Every now and then Stereophile will write negative things about a unit, and the company then immediately rebuts those critiques in the back of the issue, usually pointing out detriments of the review or set-up or something like that. But I can't remember Stereophile or TAS ever ending a pages-long review, complete with sexy photos and graphs, with something like, "Don't buy this. It sucks. You'll regret it."

Consumer Reports is the best model for reviews. They buy everything at retail and then review. Not a viable model in high end audio.
I still frequently disagree with them, but they are honest.
