Even hi-fi audio magazines are famous for pulling off REALLY idiotic stunts, like that german one that reviewed HD650s using a $300 level amp and didn't even state their source; claimed the headphones sounded "muddy" because of something entirely caused by associated equipment.
I'd trust certain RETAILERS of hi-fi equipment more than some of those hifi magazines. Especially retailers that understand the concept of "associated equipment."
The best review you'll ever read, by the way, is the one that YOU come up with yourself when you listen to the equipment that you're considering buying. The pair of ears on your head are a hell of a lot more suited to what you're most likely to enjoy than some random dude with a lot of time on his hands in an audio magazine.
For example, tastes vary so widely that some consider the HD650 to be the holy grail of listening on these boards, whilst others think they are dark, occluded, and too relaxed to be invigorating at all (both opinions are correct). An audio magazine will never state the reviewer's tastes, or at least it's difficult to figure out just where the reviewer stands a lot of times.
But that's just me, I'm lucky in that I get to hear everything before I buy (or don't buy) it.
