Matt, congrats on a very fine unit you have, the Esoteric K-01, however, even used, Be prepaired to do hundreds of hours of burn-in with each setting, this unit is not like doing a burn-in and you are done!, each setting has to burn-in, The great news here is nothing you own or your computer audio will compete with the Esoteric K-01 unit, you need to talk to other owners on the Esoteric threads!, they will validate my claims here,pm me about cables, cheers.
