Upgrade from Proac Response 1SC?

I never thought I'd be asking this, but what bookshelf speaker might be a step up from these? I've had and loved them for a little over 10 years now, but with a recent major upgrade in my electronics (will be listed at end of post) I think they're just a bit too small for what's now driving them. I've heard a pair of Sonus Faber Olympicas (way out of my price range) and some Revel M-106's (not sure they're a step upwards from the Proacs). Would like something I can live with for a long time to come, but hoping not to exceed about $3000. Impossible mission? Maybe...
Advice and suggestions are welcome. Thanks.
