I currently have my old faithful onkoyo 601 and was very impressed with  the paradigm cinema 100 speakers I heard at a sound store in Durban. I would be happy if any of u could give me some advice on were I could get a good deal on it here in s.a as the prices online seem very cheap . I would nth mind a used set as well . Thank u any information will be gr8 lying appreciated. Btw my lounge is an open plan with the lounge being a 4 m by 3 m area.
