if what you are referring to is the cross-feeding stuff to make headphones sound nicer, then HeadRoom has some docs here: http://www.headphone.com/products/faqs/about-headroom-crossfeed/ but it doesn't actually tell you exactly how to do it (obviously). My iriver hd140 also includes something similar named SRS (http://www.srslabs.com/) but it generally sounds horrible (to my ears). However they have many demonstration files available (http://www.srslabs.com/Demonstrations.asp) that I haven't had a chance to listen to yet in a controlled environment.
