here's a vague answer, since i don't own the EX1000 anymore...
It was too polite. A little laid back, smooth, romantic, boring. The treble was annoying for my ears. I know lots of people LOVED the EX1000 but it jist wasnt for me. It might be good for other music genres, but I wouldn't know.
Out of the entire collection of trance tracks i had at that time, there were only 2 tracks that were worth listening to on the EX1000....if that means anything...
But on the other hand, the FX850 is a bit more engaging, enveloping, the bass is more lively, energetic. The treble is not sharp or sibilant. Its also a smooth listening experience, but not boring in any sense.
I CANT STOP BOPPING MY HEAD. i feel like getting up and dancing almost every time
