Cary pre-amp with McIntosh amp

I'm looking for a new (actually used) amp to replace my BAT VK-60. My speakers are Wilson WP6's. Despite the reccomendations of some, I have not found this amp to work well with these speakers. In my opinion this is due to the high output impedance of the VK-60 - around 3 Ohm!.

As its replacement one of the amps I'm considering is the McIntosh 2102 (tube). (Not sure about the output impedance on the Mac, but the input impedance is 40K in balanced mode). My preamp is a Cary SLP 98P. Can anyone comment on this combination?

P.S. I live in Alaska so my auditioning options are somewhat limited.
