potentially, an amp at least for the fronts will improve sound quality. is it a "power" issue, quality of components issue, separate components issue, or all of the above? that could be debated for... you get the point. Could you also improve the quality of your system by purchasing better speakers, absolutely. if your truly looking for better sound for music, the amp won't do it, at least not alone. you'll get the amp, and then start wondering what a better pre/pro would do for sound quality, and so on. find a dealer who has your speakers set up with different equipment, go and listen, and also find a dealer who will allow for in home demos. figure out what sounds better FIRST, and then build it a step at a time. you will spend, and eventually waste, more money doing it piecemeal than finding out what exactly you want and buying it a piece at a time. i would know.
