My other post is just gone so I'm posting again. Ok, when watching a movie in 2 channel only, does the LE get mixed in? I'll be watching movies with a pair of Beyerdynamic DT770s and a headphone amp I built. THe DT770 is the king of headphone bass, it delivers more bass (It's stikk tight, fast and deep though) than anyother headphone out there. And I want to be able to take advantage of that and listen to the LFE. Ok, now for Dolby headphone. What exactly is it? Are there any sound cards that support it? What does it do? And, does anyone have a site or a list of the movies that have/support Dolby headphone? Thanks.
