Amps are not magical unicorns that decrapify everything plugged into them and do your laundry and fart rainbows. They're tools, usually intended to supply enough clean current or voltage to models with unusually stiff requirements for one or the other in order to reach volume. Alternately, they're used to add a bit of color to the sound (e.g. tubes). No ~40 ohm, sensitive headphone with a reasonably flat impedance curve is ever going to sound fundamentally different amped vs. unamped. It's certainly not going to go from crap to the food of the gods, or whatever.
The SRH440 is quite a good headphone for what it is. I've had mine for over two years and have been quite happy with it. But world beater is isn't. Now nobody would have that much of a problem with a review that said it was, even if it were obvious that the person hadn't heard another headphone to compare (i.e. all those M50 reviews a few years ago from new Head-Fi'ers, for instance). Where we have a problem is:
A) Your mischaracterization of the majority of Head-Fi when you continue to say that we're too elitist to accept a good < $100 headphone,
B) your pattern of inconsistency and boundless superlative, likely caused by lack of experience with a given model and/or "new product rush";
C) your habit of making strongly-worded posts in legitimate advice threads, only to post completely contradictory advice in similar threads one month later; and
D) your tactic of retreating into "lecture mode" whenever you're called out on any of the above by attempting to impress us with your alleged professional experience, by calling us names and/or resorting to ad hominem (e.g. "toffee-nosed elitists"*, Xbox), by continuing to assert A), and by complaining that people are picking up on minuscule inconsistencies like the difference between crap and the duck's nuts.
I think the biggest issue, however, is E) Your seeming inability to consider that maybe, just maybe, we're calling you out not because we're A) or because we're meanies or jerks or people who have too much time on their hands, but because what you're doing has real consequences for new users, who don't have as much experience as we forum regulars do and thus trust the nuggets they're given in their recommendation threads. We think you're amusing. A guy who buys a $100 headphone on your recommendation that it's the GREATEST THING IN THE HISTORY OF EVAR WITH CHOCOLATE SAUCE ON TOP, ends up not liking it that much, then finds that you've now declared it crap and are on to the next demigod headphone--he's not going to find you amusing at all.
And before you say something insensitive like, "Well he shouldn't have just taken somebody's advice on the Internet, the dip!", maybe a better answer would be to not post at all if you don't care what happens to people who read and believe your advice.
*Had to look that one up, as we don't have that where I live--fascinating etymology on that phrase, BTW
