Which Cardas cable is the warmest?

A question for Cardas interconnect users. I am currently using Cardas neutral reference between my dac and pre amp, as well as pre amp to amp. I am very happy with every aspect of sound ( detail, sound stage, timbre of instruments, highs and lows). However, the music still has a slight digital sound to it, ie; lack of mid bass, reverb and highs that are a bit too crisp. In other words, the analog sound is what I am attempting to simulate. What I am wondering is if Cardas golden reference, or Cardas golden cross would be a bit warmer? Hence getting me a little closer to analog.
I am completely happy and cannot afford to change my front end which consists of a CEC 5100 transport to a Genisis digital lens to a Parasound ultra dac 2000. The sound is close, I guess Im just looking for the warmest Cardas cable between the two. Thanks
