If you in fact need to do anything at all, consider power quality over more wattage.
Tablejockey's comment is on the money. I just did the experiment outlined in the article with a 35 watt amp driving 86 db sensitivity speakers. Only takes 4 watts to arrive at a 92 db level. As it turns out, for me, 92 db constant white noise at 1 meter is WAAAY louder than how I listen even given my listening position is 3-4 meters (not 1) from the speakers.
