Jim Clark is correct. The Ed Frias kit will definitely sound better than the Titans. It uses good Peerless drivers (Vifa's sister company) and a nice cross over. It also looks nice. IMO it's a good starter kit.

EDIT: This may be what you're looking for. I have read reviews about Ed Frias kit, and most believe it won't be outclassed by speakers costing $1000. I'm assuming this would include the Paradigm Studios. Check out http://diyaudio.com The Ed Frias kit has a big following there, and they may be able to give you more of an idea of what you can expect.
