Likewise I could find you 10 more people on this forum who would prefer the HE-500 or HE-6 over the LCD-2 because they like the small treble spike they have compared to the recessed treble the LCD-2 has. There is nothing suspicious at work, just differing preferences in audio quality.
Measurements speak for the HE-500 and HE-6 as well. Please do not counter this line with that LCD-2 measurement paper with your tapered green line, the thread's seen it more than enough.
LCD-2 costing 1000 and HE-500 costing 700 should have little to do with it. Never take price into consideration for hi-fi stuff, because half the time, something more expensive might get out-performed by something less expensive.
