Is their anybody our their who has tried to link two or three rooms to one hi-fi source? I currently have a sherwood pro-logic amp, 5 jpw speakers, a teac cassette deck and a toshiba dvd player linked to my toshiba rear projection TV. I am currently extending the house and will need to power twelve speakers from the components I already have. This will give me the same music sound throughout the ground floor of my house. I have had zero response from some hifi retailers. I had thought that by amplifying each set of four speakers, I could have three amplifiers powering each set of speakers. but how do I connect my components ???? p.s. I have a very limited budget of about £500 to spend on such a unit. Any ideas or thoughts?
