I'd love to be able to afford the Sofia IIs or IIIs but given I can't I own B&W 803D mains.
They are particular to good high current and wattage of 400 watts/channel or more and like to be bi-wired to get the best bass and overall sonics of out of them. Plus the amp has to be able to handle impedance loads of 2-3 ohms as while nominally rated at 8 ohms, they do dip to the 2-3 ohm range.
If I had the money, I'd choose the Sofia IIs but I imagine they will need more power than your current amp as well.
I have mine mated to a Spectron MK2 Class D amp with the V-Cap option and a McIntosh C2300 preamp and they sound great with the SS and tube combination. I've listened to the speakers with Mac 501 monos and while they sounded rich, there was a lot lost in dynamic impact and overall headroom and bass tightness.
