Both amps work well with the BF cabs, I use the streamliner with the midget t on most gigs...I don't do many loud gigs now. I have a 3rd BF cab on order....big baby t expected soon. Some reports that the streamliner lacks top end are not my experience, I think it is a fantastic amp. By comparison, a big band I played with, I would use the streamliner at half volume with the midget t. The iamp micro was literally full up through a Epi ul2 4x10 to get the same volume, and you could feel it compressing like mad!
