Try some tubes in the line up. The California Audio Lab Sigma I or II DAC are great buys with their single 12AX7 tube output. Or, go to a tube preamp and use the integrated as a separate amp. "Warmer" interconnects like Cardas Golden Cross Reference between the CD and the amp will alter the character of your sound as well.
A "wamer" CD goal could be a cry for a less harsh sounding DAC which is what the Sigmas provide. The cables are another nice tweak but by themselves may not be enough "warmth" you crave.
Try listening to some tubes and evaluate if they head you towards what you seek. I heard and slowly moved all the way to tubes - preamp, monoblocks, DAC, phono-stage...the tube "warmth" was seductive!
Good luck.
