What are you thinking about for the budget and new direction? And how big is your room?
I currently am running JBL Studio 580s with a Mastersound Duventi, and the Duventi gives my JBLs excellent base authority and really helped tame the top end which was an issue in my room.
The power ratings on the 4312 SE and 580 are the same at 6ohms and 90db, but designs are significantly different, so it's hard to say if they'd be a good match with the Duventi. However, the 4312 SE state they are rated to perform down to 10 watts, so it could be a good fit.
