I have a pair of Ohm Super Walsh 2.100-S-3s speakers @6 ohms(15 to 150 watts recommended) powered by the Marantz SR5003 receiver(115 wpc @6 ohms). I've been thinking about getting an amp to give the speakers a little more power, but the amp that I'm interested in is pushing about 175wpc. Would that much power be harmful to the speakers? Am I just wasting my money getting an amp? Any advice is very much appreciated.
