I think it's misleading for people here to think they're getting "audiophile grade" headphone, like the HD555. My eyes turn red when I see HD201 and HD280 listed as audiophile grade headphones. The word Audiophile has no meaning if we allow any level of headphones to be listed.
I personally don't consider my HD595 and ATH-A900 to be audiophile grade.
I believe Audiophile should be reserved for a certain grade of headphones.
but my small thought is that it isnt quite that level...if you just have a sound card and some headphones...
the people with elaborate setups...still using radiotubes and the like, with amps, etc etc...those people have truly audiophile grade sound...
..and i envy them
