What a great compressor plug-in!

I am looking for a great mastering compressor.

Something smooth, not too colored unless pushed, not too intrusive over dynamics, but can push down 1-3dB fairly transparent.

Does anyone with a few years behind this feel it fits the bill. I know there are a few outstanding comps that are better on single sources or busses, but not quite for stereo mastering. I would rather not go through the demo process, I trust you guys !
