There are some spacialisation algorithms in the H9000 starting at 5910.
One of the problems with trying to cram surround information into the stereo field is that to be effective you will often have phase coherence problems, and you need to know the surround sound configuration to attempt a conversion.
QSound have the best surround to stereo encoding technology I know of, but it certainly messes up the phase. If you have an inside line to their algorithms, I’d be happy to have a go at building them on the H9000, but they hold it pretty close to their chests.
