Greg - I listened to both of these speakers at length over a year ago. I chose the 804's because I felt they provided a more realistic presentation for jazz, acoustic and chamber music with better detail. I do listen to some pop (Steely Dan, Van Morrison) and orchestral stuff and they do fine. The mid-range on 804's is quite good. The bass is tighter and less pronounced. One drawback is that I occasionally (maybe 5% of the time) sense that the drivers don't integrate the way I perceive they should. This could the recording, however. Both reviewer's (Soundstage and 10 Audio) thought the drivers integrated quite well. I have been using various tube amps (VTL, ARC, and Rogue) with excellent results.
The 100's clearly had fuller bass. I thought there was a slight edginess to the 100's although it wasn't so objectionable that I would not have purchased them. Mids were very good. Imaging was a bit better on the 804's but that was likely due to the room and set-up.I thought both speakers were pretty musical and I could have lived with either. (In the end, my wife liked the 804's much better, but she thought she was getting a free turkey baster.)
You don't say what kind of music you listen to or what the front end is, and that could make a difference. . As always, try to audition both in your own room. Good luck.
