I use both ACR and LR to process files from a 1Ds Mklll. If you want the files to look as clean in ACR as they do in DPP, the first thing to do on import is to change the camera calibration from Adobe Standard to Camera Neutral, and reduce the blue luminance (in the HSL panel) by about 20 points.
You will then be looking at a file that looks exactly like what you see in DPP, but with the power of ACR at your disposal.
Depending on your camera choice, what you do in HSL may vary, but choosing Camera Neutral is a must. Adobe Standard is not a good starting point, IMHO.
