its not that i don't beleive in amps, its that i don't beleive in using amps for low impedance/high sensitivity phones that are easily driven by the amp of an ipod. im planning on getting an e7 sometime soon so if they REALLY make a big difference on low impedance/high sensitivity phones then my mind may change. but for now, i have to say i dont notice too much of a difference.
also, i dont mind brightness as long as its in the upper highs, some people call the ety's bright, i find it very hard to call them this since they don't really go past 15k easily, they are slightly harsh around 6khz though, but not in a good way. for the most part they are pretty neutral. they're neutral enough they make bad recordings sound REALLY bad. they are also not the fastest headphone...... over time i've discovered some irritating flaws in them, but never the less they blow my ad700s out of the water still. i find the timbre much more realistic, the ad700s sound plasticy in comparison.
I have the DT880 250 ohm and they are the brightest cans I own. The Grado Sr225i, infamous for it's brightness, pales in comparison. They are sometimes TOO bright for me though, and I only use them for audiophile classical recordings, soundtracks and movies/gaming. I read that the DT880 loses it's sibilance when paired with a nice and warm tube amp. I might try this in the future.
To me, it sounds like you're gonna love the Fostex T50RP. They're the most neutral cans I've heard so far. They need an amp though, even if you don't "believe" in amps. :) Remember, headphones are speakers. Speakers need amplification.
