hello. I'm currently working on setting up audio throughout my house. Basically we are turning it into a party house. we are college students on a somewhat of a tight budget. we are going to use either 6.5 inch or 8 inch ceiling speakers. music will either be played from the wii ( streamed over network) or played from my media server controlled via mpd. Ive been searching all over for a receiver and or amp that will work best for this. We want to have a total of 6 speakers throughout the house. it would be nice to be able to turn either individual or a group of speakers on or off (not required tho). One of my questions is : do I even need a receiver? Or can I just use an amp? The output from the wii or media server will be RCA audio out. I don't need anything real fancy, the most important thing is cost. Any help would be greatly appreciated. thanks.
