An amp with high power and current is ideal. While the Wilsons are highly sensitive, their impedance curves can be tricky, and are rated at a nominal 4 Ohms. The person from whom I purchased my 3/2s (which were upgraded by Wilson to bring in spec with the 5s) drove them with Levinson 434s, fed by the 390S CDP / preamp. That seemed to be a pretty good match.
