What about the famous headphone reviewer ... Dale Thorn ?

His DT48-bias is an issue for me. He is a midrange lover like me but the grains of salt are large with him...

Removing more people from the list, I also don't trust people that listen with their eyes.  There are so many people that, I think, already know what buzzwords they're gonna use before they even listen to a piece of gear.  That could be subconscious, I'm not sure.  Are there tubes?  Talk about warmth.  Solid state?  Say it's harsh.  Does it measure very well?  Say something about it being 'sterile'.  Is there wood involved? Mention it sounding 'organic'.  This goes on and on.  I've even noticed what seems to be a pretty high correlation in terms used depending on the color of the gear (copper colors > silver, manufacturers).

"The perceptual ambiguity of wine helps explain why contextual influences—say, the look of a label, or the price tag on the bottle—can profoundly influence expert judgment. This was nicely demonstrated in a mischievous 2001 experiment led by Frédéric Brochet at the University of Bordeaux. In one test, Brochet included fifty-four4 wine experts and asked them to give their impressions of what looked like two glasses of red and white wine. The wines were actually the same white wine, one of which had been tinted red with food coloring. But that didn’t stop the experts from describing the “red” wine in language typically used to describe red wines. One expert said that it was “jammy,”5 while another enjoyed its “crushed red fruit.”

Another test that Brochet conducted was even more damning. He took a middling Bordeaux and served it in two different bottles. One bottle bore the label of a fancy grand cru, the other of an ordinary vin de table. Although they were being served the exact same wine, the experts gave the bottles nearly opposite descriptions. The grand cru was summarized as being “agreeable,” “woody,” “complex,” “balanced,” and “rounded,” while the most popular adjectives for the vin de table included “weak,” “short,” “light,” “flat,” and “faulty.”"

Headfonia has been one of the most dangerous sites for me since I started this hobby, since they occasionally have enough criticism that I think they are being objective, but at the end of the day that's not always the case.  At least they have the guts to do some comparisons from time to time though.

I think headphone.guru and 6moons are the biggest jokes for me.  I sometimes read over 1000 words in a review and feel like I learned nothing about the actual piece of gear.  6moon is hard to take seriously to begin with, but I actually was introduced to this hobby by googling MLE's gaming thread on head-fi; so when he started doing reviews on guru, I naturally took a peak at their other reviews.  Their overall lack of criticism and comparisons really drives me batty (see their recent Ether review).

I don't know about 24bit and his Flare IEM thing, but I appreciate headfonics for their boldness to be critical when most other sites aren't.  24bit is pretty clear and up-front about his preferences (he doesn't like clerical, analytical sound signatures and instead prefers warmer headphones with good bass impact) and that's why he doesn't like many otherwise popular headphones.  I never get the sense that he's shilling for views or free goods, but maybe that's just me.

I'm always interested to find trustworthy review sites though... inearspace seems quite interesting.  I am currently looking for an upgrade over my 400i to pair with my new HA-1, and I had been considering the PM-2.  Almost every review site gave it glowing reviews, yet when I actually spoke with owners via PM (forgive the wordplay), most of them were less appreciative of the cans, especially in the treble region.  It's refreshing to see that inearspace gives the PM-2 an equally honest review.  Guess I need to continue my search for 400i successor, hah!

Yeah, I'd say extraordinary claims require extraordinary evidence. Screenshots.
