The Boss (aka "Keeper of the Finances", "she-who-must-be-obeyed" or "And just who bought the Isobariks, anyway?") has (I think) given me permission to buy a new pair of headphones (she wants my Senn HD420 to use on her electric piano!). So Boys and Girls, I need some help here, what's the current "flavour of the month" for headphones? And, of course, a headphone amp to drive them (the Linn Kairn preamp does not have a headphone socket, but has three line outputs). total budget for phones and amp is around £500.
