Apparently, these work well with Avantgardes: (http://tomevansaudiodesign-usa.com/_wsn/page4.html) You might inquire from these guys as to the combo's traits, since they sell both lines; (http://avantgardeaudio.com/index.html) Any high quality SET amp will work well. Keep in mind: Any noise/system shortcomings will be magnified as if by an electron microscope. These speakers are unmerciful in their adherence to the truth.
