I just took my Pass Labs XA160.5 to a friend's system. He has the Sashas and a Pass XP-30. His room is medium size and we played the music load but not ear-bleeding levels. We played a variety of jazz, pop and classical, vinyl and digital. The XA160.5 was an excellent match for the Sasha. In fact, the speaker was very well controlled and it was the best bass that I have heard from his system. So based on today's experience, I have to disagree with those who don't think the XA160.5 has enough power for those speakers. It was a very memorable listening session.
