I'm comparing these modes to DPL-II on my 7300 OSE. I've only had the 7300 for a few weeks (bought used) to replace my 6200 and haven't reached many conclusions yet. On the 6200 the differences between CS 5.1 and DPL-II were obvious, with CS giving greater separation. With the 7300 its a little more difficult. Does anyone have an opinion on what mode is best for given material (action vs. drama, etc.)?
