Maggie will tell you that plenty of tube amps are the best matches. The best I've heard them was with big Rogue monoblocks. OTOH, a number of dealers show Maggies with Mac solid state amps...If you are into Mac, that's an option. The big BAT ss amp is an option too, but I certainly wouldn't call it making your system simpler.
Most folks suggest integrated amp when poster graves simplicity, but I would say that most often power amps barely get touched by a secondary user. It's all preamp user interface/experience that makes joy for a secondary user. Cheers,
