What amp to pair with ARC LS15 and Magnepan 1.6s

I need some suggestions as to what amps to audition to go with my system. New or pre-owned. Max I can spend is $4k.
Audio Research 100.2

Rogue Magnum 120's or 150's

Had them with your set up...can't go wrong.
agree with the above on the rouge... try to get models that are within one year old. there were some parts and relaiblity issues with some older one.

if looking for solid atate -

pse studio V signature mono's( hard to find, but this is a well regarded combo)

classe cam monos

herron mono blocks.

hope thar helps,
