Those are pretty harsh comments, i guess that's the risk was taking, speaking good about the PS1000 out of the shelter of the Grado fanclub.
For my part, i think that the LCD2/3, HD800, T1, and HE500 are all very good sounding headphones, i just happend to prefer the PS1000.
And speaking of high price of admission, i feel the same way about the Stax 007/9, they're good, but overpriced., especially when you consider that they need a dedicated headphone amp.
The PS1000 on the other hand could sing even if they were plugged directly in a canary's butt.
