My father finally decided to do his housewide audio system correctly and use separate amplification for each channel instead of an impedence matching speaker selector distributing the power. The question is, what are some good choices in amplification for such a system. Preferably I am looking for 6-8 channels of amplification, and not something too powerful (probably 30-40 watts per channel, or less, should do fine for his listening habits). I have not seen many amplifiers that fit his needs (though I am probably looking in the wrong place). Price is not that big a deal, but cheaper is always better, as my father is more of an avid listener and not an all out audiophile so really high end gear would be overkill for him.
