Thanks, very much appreciated!
I am actually pretty impressed with the sound of Reason. I am using the MClass stuff on the master buss, not too much; i.e the EQ, Stereo Imager, Compressor and Maximizer. Like I said barely use the compressor and maximizer. I then loaded it into Wavelab and quickly mastered it there, but didn't do anything with imaging. That all comes from panning the instruments and the stereo imager in Reason.
I do mastering as a part-time job, but this track really didn't need a lot of treatment. A simple highpass filter set to 20Hz, and some limiting; that was it.
