Paradigm Signature S2 v1 Amp

Just picked up a pair of Paradigm Signature S2s and now need a solid amp.  Been browsing for decent deals, because I don't want to break the bank, but definitely want to best I can manage for the Signatures.  Hoping to keep it in the $1k ballpark, maybe a bit more if worth it.  Unfortunately, I don't have much experience with different brands...but I've narrowed it down to the following:

Peachtree Nova150 Integrated amp (or Nova300 if deemed worth it)
McIntosh MC122
Linn Klout

appreciate any help here, open to suggestions, thanks!!
