My experience with Paradigm Reference speakers is that they can sound excellent, but the quality of upstream components is key.
It's amazing what these speakers can do with high quality sources, cabling, and recordings. I think you're doing well for speakers in this price range, especially if you add in their excellent Servo-15 or similar. I can't recall if the S-15 has a continuously adjustable phase control, but if it does, it can help you with nailing the sub imaging right between your mains.
I think what I'd do if I was you is make sure you have your speakers on good heavy stands, then put extra into raising the quality of the other pieces. Cables might be a good start if you don't have quality ones yet.
