I know what you mean, but the guy who posted that video seems to go out of his way to use pretty extreme settings on everything but CMSS-3D... Did you watch any of the videos posted by Fegefeuer after my post? Those are much nicer, though expect a real card to sound even better during gaming, than in a YouTube sample.
Don't get me wrong, CMSS-3D is great for positional accuracy when configured well, but don't knock the other DSPs yet.
I have a TiHD, so that may contribute to my bias, but I'll have to try some others. I do agree it can sound a bit unnatural at times. I'll have to experiment to see if there are more natural sounding options, especially for non-competitive games and movies.
Philips Fidelio X1
Fun: 9 (Amazing)
Competitive: 8.25 (Great. If the bass were a little tighter and more refined, the X1 could've been a 9 in competitive, though it may have reduced the fun factor)
Comfort: 9 (Amazing)
Very nice review. The X1 is the type of headphone I could convince a non-audiophile to drop that kind of money on just based on how nice it looks.
