I have owned a pair of 803 matrix since 1994. While I havn't compared them directly to 804s, I would expect the 803s to be a bit better in the bass and overall soundstage. I initially powered them with the Adcom 555 MKII and was very happy with the quality of the sound (rock, folk, reggae....). I then bit the bullit and bought a pair of McIntosh 501s. The resulting difference was simply astonishing.
I will also note that I felt the 803s actually got better and better over time; well after the break-in period.
I am curious what price range you are finding for the 803s. I have an opportunity to buy a pair of 801s (series 3), the owner of the 801s wants my 803s but I am uncertain about their approximate value. I would assign a 7 out of 10 for condition (two small scuffs on the lower left of one speaker otherwise perfect).
Speaker preference is about as subjective as anything can get, so listen to all that you can at home if possible. I can, enthusiastically recommend the 803s. Best of luck deciding which is best for you!
