I have 5 sets of in-ceiling speakers (Polk RC80i rated at 100 watts). They are connected to a Niles SP-6 Speaker Selection System and out to a Yamaha DSP A-2070 (my old HT work horse) I am connected into the Main left and right which is 70 watts. I use this for music CDs, FM radio, and MP3 and DVD recorded music. The Yamaha is there because I have it.....should I be looking at something else for my set-up. Any comments welcomed. Thanx.
