I don't know what kind of cd player you have. I have briefly owned a sigma. It was very detailed and dynamic. However, it was not smoother or richer sound than the dac I already had, a Micromega Duo BS2. If you're looking for something to smooth out or warm up a clinical sounding cd player, I do not think a sigma is the answer. Suggest you try some rich sounding interconnects, such as MIT or Harmonic Technology before adding a dac.
