A friend of mine is having a house built. His HT will be in the basement. He is running a seperate music only system on the main level. There will be 4 sets of in ceiling inwall speakers in 4 different rooms. He is getting volume control switches in each room. I need help in 2 areas. First, what kind of speakers do you recommend? He wants good sound and decent volume. Second, what should he use for amplification? The only source he will be using is a cd player, maybe a tuner. Should he get a receiver with a speaker switch box or some kind of multichannel amp? I don't think they care about playing different sources in different rooms. Any help would be greatly appreciated.
