If you've only had the gear for 6 months (which I'm assuming because of your comment about being into high end for 6 months) and you're happy with the 803s then why change?
If your priority is stereo (by which I assume you mean 2 channel) reproduction, then you might want to ditch or sideline the Rotel 1098 and leave it for HT processing, and bring in a dedicated 2 channel preamp or integrated that has a HT Bypass or pre outs.
I don't love the 803s, but if you want to attain some accurary and better sound, then I think the rotel is holding you back(BTW, I've never heard of a speaker loosing accuracy if you play it loudly for an extended time. A speaker is either accurate or not, depending on the associated gear). Also, you never mentioned what your amplification is, but in another post you said you were using Krell, which if assuming it a 2 chnl amp or monos should be fine.
I wouldn't spend the money on speakers until you deal with the pre/pro seciton, but there are a pair of Verity Audio Parsifal Encores for 8500, which is an amazing price for these speakers. They're not wood finished (piano black) but these speakers are 20 grand new, and sound every penny of it. Some like the Sonus Faber Cremonas, which are a step up from the 803s, but they're pretty big. There's a pair of ProAc Response 5 in the optional ebony finish 8000 and that's a pretty great price for these lovely speakers.
My recommendation: get a real preamp first, then see if you still want to change the speakers
