I like this style of music as well. I've been listening to Two Steps From Hell's new album Archangel recently, as well as their earlier Invincible and Thomas Bergersen's Illusions. There's also Immediate Music, Globus, and X-Ray Dog that work in this style as well.
I also just picked up an album by Jochen Flach and Lorenzo Piggici off of iTunes that's not bad, either (though TSfH is better). I may pick up some of their other work, too.
