I owned Carrera BE's for over three years and have owned speakers with the same drivers as the Carbons. Which speaker model you chose will determine the best amp for you as their voicings are not the same. As was recommended several times just call John(Fritz} and ask his advice. He has personally owned and used integrated amps from Belles, Kinki, Van Alstine and others for SS but he does seem to prefer tubes with the Carrera's in his own system.
