I generally agree with Tvad & Clio09. CDP/DAC is not the optimal place to get a "full, warmth, rich sound."
These are euphonic colorations that are not in the digital source but will come with your preamp and amp.
I am firmly on the fence when it comes to which sound I like best: rich and warm (euphonic) or detailed and wide open (accurate)--please, no arguments about the characterization or semantics; I am having enough debate with myself as it is.
So I use the most accurate CDP/DAC I can afford and switch my preamp/amp between tube and solid state depending on my mood. This way I can have my cake and eat it too. Remember, you can color the sound of your source downstream but you cannot take the color out.
