Classe CAP or NAD???


I am considering NAD S300 (100W) or Classe CAP 101 (100w) CAP (150w) for Thiel 22 and Arcam 7SE. I know audition at home is very important for choosing system, but my small town has only circuit city. So, I need your advice via this forum. NAD S300 is heavier than Classe CAP 151, but Classe is considered as good matching with Thiel. Also should I choose Classe 151 only for the more power than Classe 101? Thanks for all your comments.
