I use Ozone for some things, and it works well. For others I use Samplitude's mastering tools (multiband compression, eq, etc...)
You may want to do your final work using several different listening systems...for example, I will audition my final passes through nearfield Tannoy Reveals, then thru some bookshelf speakers (RCAs...actually good little boxes!), car audio speakers in a box for home use, and through the home stereo (Bose and Pioneer speakers)...instant switching really helps to get an A/B comparison...
I make sure to listen to everything through both stereo and mono playbacks, too, to correct any phase issues. What sounds great in stereo may just disappear in mono
