What's Next?

You say you want to build your system around great speakers, and that's your choice. A lot of people do that. It's great when your refined, revealing, transparent speakers show you everything your source can do. But if you can hear everything your source can do and you're still not satisfied with your great speakers, well, it could be time to look at your source.

Personally I would be happy with any of the speakers Mimberman suggests, especially the Parsifal Encores (and that is a great price, wish I had it lying around). But not to dress it up too much, any of them would be slumming with a Rotel CD player. Sorry.

On the other hand, if you purchased the kind of CD player that made your 803s blush, THEN you would be ready for new gear downstream.

I only can echo what Mimberman and Tobias said. Your electronics are holding your speakers back. I believe in source first principle. If it ain't top notch from the beginning, it won't be at the end. Your speakers are only reproducing what they are fed, and they should be able to handle a significant upgrade on the fron end.

I'll chime in along with Mimberman, Tobias and Muzikat. I built a system around a Rega Planet (original) cdp. If you read the comments in my virtual system post, you'll see how the source-dollar-ratio was out of whack. I thought I had synergy, but I didn't. I regret having waited on upgrading my source last. I've gone through some great speakers looking for "the" sonic signature while it was my source holding me back all along.

Source or speakers, either can hold you back if not approx. the same level. I know that's quite a nebulous statement, but it's a big factor.
If you're bound for speakers, I am currently enjoying the Eminent Technology LFT-8A's. I have used Vandersteen and Magnepan speakers in past.
Try to audition whatever you will purchase; not always easy. You can always go to audioreview.com to see what others have to say. I have found it a good source from objective owners. You will be able to note their equipment, as well as discussions of their upgrades. Note especially the ratings; components with high ratings and numberous reviews are truly standout performers. Hint, hint, look at the Eminents!
Of course, now that you've gotten good advice from our other posters, you'll have to eventually upgrade the source too. It never ends. The best you can hope for is a remission in the disease's progression.

Oh yeah...I hadn't even looked at your source. If what you want is to get good 2 channel sound, then you don't need to upgrade your speakers right now. I'd start by maybe getting a good integrated (there are a thousand threads on this, and I myself am looking, so you can check out my list of hopefuls on my system page if you want, or just poke around here) that way you don't have to commit so much money to seperates (not to mention the extra cables) and see how that works. You didn't list which model cd player you have, but I assume since the rest of your gear is HT that it's a dvd/cd player. I'd say concentrate on the cd and amplification sections and leave the speakers for last.

That being said if I had the loot right now I'd buy the proacs or fidelios (def. the fidelios, but bummer about the black finish).
