on behalf of a collegue at work..... Having recently moved house and decorated our front room with a modern look I feel my old home cinema set up is going to ruin the look of the room. I'm therefore considering options open to me to replace my Kef speakers (q15 Fronts, q85 Rears, 90C centre, PSW100 Sub) A friend has the modern looking speakers from the Sony DAV800 package available for sale including Sub and I was wondering if there are any reasons why they would not be compatible with my Marantz 4200 AV amp ? I'm assuming the speakers will take standard cable and although not as acoustically good as my current speakers and sub will offer good enough sound reproduction for film / audio playback. He got a full set of replacements free so has all the speakers (18mnths old) for sale - Do people feel £100 is reasonable for kit that's surplus to his requirements ? Any advice on this matter greatly appreciated.
