This is interesting. The Paradigm is a brighter speaker but your gear is tailored to temper it so I think that your system is well designed. This means your should probably stick to speakers with a more forward sound profile. Certain brands mentioned above (Spendor, Vandersteen, etc...) are much warmer than the Paradigms. You may find that your system could be a but dark vs. what you are used to with some of these options.
I really like the Kantas and the Sopras. I think they are brilliant and would work well for you. I am not sure how much better the Kantas would be but the Sopras are definitely a step up.
Other options:
Magico A3
Used Magico S1 or S3s
Used Vivid Kaya 45 or new if you save ($18K USD)
Used YG Carmel IIs
Used Wilson Sabrinas or new they are a stretch like Kaya 45
VonSchweikert Endeavour e3 MK II
The most musical on this list are the Vivids and the Wilson's in my opinion but lets remember that my opinion is worth what you paid for it. They are worth trying to hunt down though.
