I thought I'd share my setting with the community, just in case someone would like to try them. Different room, different speakers and different receiver settings may be a big factor in these not working for you, but here it is anyway, for someone that may be having trouble getting the best sound out of their system. You can always start here, then tweak away. If this helps someone, please let me know. If not, please don't throw eggs.
