The "how many reviews it got" rule


This is my rule of thump when I purchase components online
without having heard them first.  If a component received a
lot of reviews, chances are the component is very good.
I mean the component has to be good to attract a lot of
reviewers. Most reviewers probably wouldn’t
bother to review something he doesn’t like in the first place.

Uh, there are perfectly good reasons why magazines won’t write negative reviews. 
^^^^^
True. I can't speak for anyone else, but I have to remind myself every now and then that just because a particular component doesn't make a "Recommended Components" listing doesn't mean it can't hang with the ones that did. Perhaps it just didn't get reviewed.

There are myriad manufacturers out there and a finite amount of review space. Especially review space by knowledgeable and articulate writers.
I bought a component based on really great reviews in both stereophile and TAS. It cost $2,300 and was a new DAC. I compared it to my then ten year old (bought for $250) used DAC. they were the same. i spent two weeks trying to figure out why the new wonder DAC was no better than my old thing. I returned the 'new' marvelous DAC.   I continued to use that old DAC for another 8 years.                
Recently my dealer loaned me a $7000 SACD player/DAC. it was better than my old DAC. NO reviews of my new player. Gee? I bought it.
