The theroy with the NS 10's is that they sound shit, so if your track sounds good on them, then it will sound ace on other systems. I cant stand the harshness of them personnally, really trash sound, sort of like a guitar amp Especially since the studio i use which has them, also has a pair of Genelecs next to em :love: But then again, i know people who swear by them, so its all personall preference at the end of the day.
