I'm using a Classe CA-100 on my AE's with good results. IMHO, the amp has a just slightly soft top end. A good match for the AE tweeter which is just slightly hot sounding without loss of detail. The amp has enough current to drive the speakers as loud as I've dared to push them. Good bass. Much better in all respects compared to my previous amps: B&K ST-140 and Adcom GFA-545.
