Well, my system is pretty much complete now. But I've been pondering the possibility of adding a power amp to the mix - perhaps a three channel to cover the three front speakers. Whether I do three or five channels, I guess my my question is, will I truly realize a worthwile difference with such an upgrade. I currently have a pair of M60s, a VP150, two QS8s an Hsu VTF-3 and sooner or later there will be either an M22 for channel six or two M2s for channels six and seven. The receiver is a HK/525 and the DVD is a Yamaha DVD-S2300. Thanks in advance for any advice.
