Agree with a perhaps moderated post that the HD-800 in it's stock form is sort of bright-ish and analytical. Dunno about the uber-transparency qualities of the GSX2. I though it was a little analytical, but I would have to try some more cans with it to determine that. Some others might have already done that though, and don't think other amps I listened the HD-800s with made it so painful.
