Popt for one of the Sontic T amps.Son of T IO think the $100 model.Your not going to get muhc volume at $100 or but there are rated 15 and have 3-5 usuable watts.Just don't remember how sensitive your speakers 93=4 db shopuld be able to work.Or get a Harmon Kardon 2 channel reciver of recent vintage cheap.I find their best of cheap recivers.
