Update: Sold my HD555's to sav5716 and purchased a pair of AH-D2000 and a set of cables for the D7000's to replace the stock cables. I think these will keep me busy for a while because of the possible mods and upgrades.
you won't be disappointed. the D2000's are creamy and relaxed, i loved them. modding them makes them even cleaner, and my god i'd say they're most comfortable headphones i'd ever worn.
comfort's not the only thing though :: looks at K1000's ::
