I heard the Wilson Cub 2's probably about 10 years ago. They were being driven by Ayre electronics and the source was a flagship Sony cdp. To this day the Cub 2 remains one of the fastest box speaker i've heard. It does have a "pro monitor" sound that I would try to tame. I would look for an amp with some warmth/texture and capable of creating a big 3D soundstage. Of the amps you mentioned the Pathos would be my first choice.
Integrated amp for Wilson Audio Cub 2's
Recently purchased a pair of Wilson Audio Cub 2's here on Audiogon. I currently have a Harman Kardon HK990 integrated that sounds nice on them but I am looking for a little higher end integrated. I am interested in the Audio Research Vsi60, the Ayre Ax-7e or the Pathos Acoustics Logos. If you have any experience with this combo and would like to voice you opinion feel free.
My current system:
Wilson Audio Cub 2 w/factory stands
Harman Kardon HK990 Integrated
Oppo BDP-105 Universal player
Isotek Evo3 Sirius Power Center
Shunyata Ztron Anaconda Speaker cable
Shunyata Ztron Anaconda Balanced Interconnects
Shunyata Ztron Python Power Cables x 2
