I use a triamped system. I have an Altec-Lansing 3-piece which I supplement with a keyboard amp. A 20-watt one for small rooms and a 150-watt one for bigger rooms. It seems to me that the subwoof carries the bottom and the satellites carry the definition and intelligibility. The keyboard amp carries the midrange, and this comes across as the perception of loudness. If I am not loud enough, its the K/B amp that gets turned up.
