I think that in my very uninspiring room (which could make even several thousand $$$$ Adam's sound bad), they sound very nice.
If I could treat the room somewhat (good luck making something acoustically useful out of a bedroom - think playing tetris with furniture and bass traps etc.) I bet they would sound fabolous!
They pack very nice amounts of deep bass, no need for a subwoofer at all... if I stand on the other end of the room in the corner.
Where I sit, the bass is ... well, not enough, at all. Which is something I'm hoping to sort out by DIYing some bass traps.
I've managed to improve the stereo imaging by throwing blankets at the first reflection points (very ghetto, but whatever) so now the music has that third dimension - depth...very cool, something I never got from headphones. And the stereo imaging and highs are probably these speakers best points, if you set them up perfectly and put them in an equilateral triangle with your head, then the speakers are lost and you are left with this field of music where in well mixed music you can actually be tricked there are things coming from behind you, above you, bottom left etc., there is so much depth and dimension.
And this is on a Realtek 889 in an untreated room. I don't know what they could do with a proper source and a good room, but I bet it would be mind-blowing.
P.S. The ALC889 codec is really cr*p. I can hear my hard drive, mouse movements, graphics card, scrolling, etc. through the speakers. So much internal noise.
