Based on your music preference alone I would go with the LCD3. The HD800 would sound really thin and harsh with modern pop and rock. Anything Audeze would render a much more enjoyable listening experience with below par recordings. Besides you love the Audeze house sound so why change? One thing though, I've read that the O2 doesn't drive the LCD3 well, you may want to look into that.
