FWIW I'm driving a pair of Dynaudio Sapphires, a similiar but not exact technical match for Sophia, with this amp.
The room is not "large" but as others have posted, the amplifier has plenty of guts and should drive your Wilsons fine albeit not to paint peeling SPL.
I also drive the Sapphires with a pair of Bel Canto Ref1000M (1000WPC into 4 ohms) and at moderate SPL they provide no better bottom end control than the Pass XA30.5.
YMMV
