i don't think it's a matter of being pretentious, it's a matter of getting the best sound quality for what you paid for. i have a pair of KRK8's, and i can remember the first time i played the cd version of quaristice over the speakers. it was a night and day difference from the leak. granted, most people listen to music on their $30 pair of headphones over their computer's built-in sound card. in that case, it won't matter what quality the source is. i don't mean to come off sounding like a deranged audiophile, but i strongly believe that autechre sets a precedent for sound quality that is rarely matched in today's music. and i KNOW there has to be more crazies on this board that agree.
edit: also, what panz0r said is right. listen to plyphon at high volume with studio monitors, and it's sort of like upgrading zelda's wooden sword to the master sword.
