The 4b (I had an st on 3.6's) is good but not enough power for the 3.6's IMO. I kept blowing the fuses and the 4b ST. Changed to a Levinson 332 and was floored! I never knew the maggies really delivered untill I got the levinson. However Bryston's are great if you get enough power. Maggies require a real world amp such as Pass, Krell, Levinson or Bryston if you get enough amp.
