reno

i just purchased a small house and my wife and i are trying to make the best of the small space. i currently have an NAD receiver and cd player and klipsch speakers (sf-1). i am going to move the entire set-up down stairs and finish the basement off. i would like some advice on buying another set of speakers that i could place in the corners of the living room upstairs (perhaps mounted high). something that will give me good sound without the other 2 speakers (downstairs) being on. thanks
