The OP clearly asked for a JUMPING OFF POINT.
With any unfamiliar tool, presets can be a great help. Simply cycling through a bunch of well conceived ones can explain a lot about how the tool works.
I think it would be great if, in addition to including exemplary presets, SONAR included little production notes for each, explaining why the particular settings were chosen, and which parameters are most likely to be usefully tweaked for the target application.
For every SONAR user ready to debate the merits of different dithering algorithms, there are likely several more for whom EQ is a new idea.
