I finally had a short demo of the 684s with some audiolab gear and loved em although with one or two cds, not my own i might add they sounded thin and tinny hopefully just the cds. Any way have read a few reviews which have all been good though some did state a harsh treble on some recordings just wondered how bad it is as my monos sound crisp and hoping this wont be a problem as ive set my heart on the 684s. Any help anyone? ?
