My EMM CDSD/DCC2 with the Stax Omega 007t headphone system is glorious, with all images well defined and little or no harshess or hashiness on any kind of music, even lesser-quality recordings (popular music). The Staxes can sound buzzy or weak or bass-shy on lesser-quality CD players. The sound is better through the direct line outputs of the DCC2 (as opposed to the preamp outputs) into the Stax amp.
