I prefer low feedback,high current amps. The brands that come redily to mind(without spending an arm and a leg) are AVA, Monarchy Audio,and the amp/preamp section of the Magnum Dynalab MD-208,but that is just me;your tastes may differ.
Allow me another personal opinion. The acoustics of the room and speaker placement are important with panels.
