If your system still sounds good to you "keep it" as is. There's a lot of people on the 'Gon who are basically into "upgrading" just for the sake of upgrading. As for your speakers being "outdated", who makes/made that determination? The biggest change to speakers IMHO has been in area of "voicing". Before you get another set of speakers you may want to consider, are you going for better or just different? Quite often, different is what you're really getting, and that may or may not be better. Many people have gotten rid of some great speakers, to get something supposely better, only to find out "down the road" that they would been happier keeping what they had orginally.
