This kind of thinking, to me, is problematic. It reads like you're dismissing some reviews as needing to be "taken with a grain of salt" because they're enthusiastic and positive, while claiming that other reviews are more honest somehow because they bash a certain headphone.
I agree that Skylab's reviews are really top notch and that he puts a lot of effort and thought into them. He has a lot of respect around here, and he certainly deserves it. However I think it's wrong to automatically dismiss the other reviews that have been posted here as being somehow untruthful or deceptive just because the people posting them are enthusiastic about their purchase.
It's probably a sound idea to approach reviews with caution when a lot of money is involved, yes. There is unfortunately truth to the assertion that people have buyer's remorse and will, on occasion, exaggerate the worthiness of a product in an attempt to feel better about said purchase or, in the worst case, maliciously trick others into making the same mistake.
I think some people around these parts have a tendency to overdo these accusations however. All opinions expressed in our hobby--whether they're made by someone with a post count of 3 or by Skylab--- are merely preference. All preferences should be taken with a grain of salt. That should be the first law of our hobby, a guiding principle we carry with us at all times lest we get buffeted about by the winds of passing fancy.
Being able to criticize a product in spite of the money invested in it is surely the sign of honesty, but not doing so isn't automatically a sign of dishonesty. In the end, the only way to know for sure is to listen for yourself. Basing your opinion off of one glowingly positive review is in no way more folly than basing it off of any other one review, in my humble opinion.
